Book excerpt: Heat Transfer XIII: Simulation and Experiments in Heat and Mass Transfer contains the proceedings of the thirteenth conference in the well established series on Simulation and Experiments in Heat Transfer and its applications. Advances in computational methods for solving and understanding heat transfer problems continue to be important because heat transfer topics and related phenomena are commonly of a complex nature and different mechanisms like heat conduction, convection, turbulence, thermal radiation and phase change as well as chemical reactions may occur simultaneously. Typically, applications are found in heat exchangers, gas turbine cooling, turbulent combustion and fires, fuel cells, batteries, micro- and mini- channels, electronics cooling, melting and solidification, chemical processing etc. Heat Transfer might be regarded as an established and mature scientific discipline, but it has played a major role in new emerging areas such as sustainable development and reduction of greenhouse gases as well as for micro- and nano- scale structures and bioengineering. Non-linear phenomena other than momentum transfer may occur due to temperature-dependent thermophysical properties. In engineering design and development, reliable and accurate computational methods are requested to replace or complement expensive and time consuming experimental trial an error work. Tremendous advancements have been achieved during recent years due to improved numerical solution methods for non-linear partial differential equations, turbulence modelling advancements and developments of computers and computing algorithms to achieve efficient and rapid simulations. Nevertheless, to further progress in computational methods requires developments in theoretical and predictive procedures – both basic and innovative – and in applied research. Accurate experimental investigations are needed to validate the numerical calculations. Topics covered include: Heat transfer in energy producing devices; Heat transfer enhancements; Heat exchangers; Natural and forced convection and radiation; Multiphase flow heat transfer; Modelling and experiments; Heat recovery; Heat and mass transfer problems; Environmental heat transfer; Experimental and measuring technologies; Thermal convert studies.

This book was released on 2012-12-06 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: The planning for the IUTAM Symposium on Adiabatic Waves in Liquid-Vapor Systems began in May of 1986 in G5ttingen. The Symposium was held in August of 1989 in the Max-Planck-Institut fUr Str5mungsforschung. The invitations to participants suggested that the written papers concern Fast Adiabatic Phase Changes in Fluids and Related Phenomena. Particular topics suggested were: Liquefaction shockwaves and Shock splitting; Evaporation waves; Condensation in Laval nozzles and turbines; Stability in multiphase shocks; Non-equilibrium and near-critical phenomena; Nucleation in dynamic systems; Structure of transition layers; Acoustic phenomena in two phase systems and Cavitation waves. All of these topics should have been treated with emphasis on physical results, new phenomena and theoretical models. Participants from fourteen nations took part in the Symposium and presented papers which were within the range of suggested topics. The organization and execution of the Symposium was performed by the Max-Planck-Institut fUr Str5mungsforschung in G5ttingen. In particular, the meeting has been promoted under the leadership of Professor Dr. E.-A. MUller, who has for many years given his support for international exchanges in science. The detailed work of organization up to and during the Symposium was in large part due to Dr. T. Kowalewski, who served as Symposium Secretary.

This book was released on 2020 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flash evaporation or flashing is an evaporation phenomenon caused by a sudden pressure drop sufficiently below the saturation pressure. Due to this sudden drop in pressure, the liquid undergoes a quick phase transition and the sensible heat of the liquid converts into latent heat of evaporation. An accidental release of pressurized liquid from supply pipelines or liquid storage tanks can generate a flashing jet with violent phase change. This fast phase change can cause rapid mixture with an oxidant like air, and if the liquid is flammable, disastrous effects such as explosions, fires, and damage to industrial equipment can occur. On the other side, flash evaporation can be beneficially employed in industrial applications. It can have a significant effect on the performance of many devices (e.g. injectors and reactors). The understanding of the fluid behavior of the flash evaporation and the resultant shock waves can help to prevent disastrous consequences that may occur due to accidental fluid release as well as can be useful to further develop the phenomena's industrial and technological applications such as utilize resulting shock waves in creating useful compression.This work investigates spray flashing evaporation phenomena and resulting shock waves experimentally and numerically, considering pure water as working fluid. 2D transient simulation was conducted by using Ansys Fluent to simulate the multiphase flow field in the evaporation zone. The Mixture model was applied using the concept of slip velocities to model multiphase flows as non-homogeneous multiphase model where the phases (liquid water and water vapor) move at different velocities. In addition, a rectangular vacuum chamber connected to a circular nozzle was used in the experiments. A z-type Schlieren technique with a Photron high-speed camera was used to observe the propagation of the moving shock wave and the flow. The numerical simulation results show that once the superheated water is injected in the low-pressure environment, the flashing phenomenon occurs and a shock wave is induced. This shock wave is a moving shock wave and it travels forward into the vacuum chamber. The two-phase mixture expands behind the moving shock wave that travels faster into the water vapor. The entire flow characteristics such as pressure, velocity, Mach number, speed of sound, density, and volume fraction are discontinuous across the shock wave. After the moving shock wave strikes the end of the vacuum chamber, it reflects from the wall as reflected shock wave that propagates back into the chamber, further increasing the pressure behind it. An experimental work was carried out with injected liquid water having an initial temperature ranging between 40 and 100°C and vacuum pressure ranging between 4000 Pa and 10000 Pa. To show the shock wave structure, the Schlieren technique was used and Schlieren photographs were mathematically filtered using the Image Processing and Analysis in Java (ImageJ). The experimental results were in good agreement with the numerical results, confirming that once the superheated water is injected in the vacuum chamber, it flashes directly and can induce a shock wave. The results confirm that with increasing superheat of the injected water, the flash evaporation accelerates. At low vacuum pressure, full flashing occurs, and a shock wave is induced especially with a high initial liquid temperature.

Available in PDF, EPUB and Kindle. Book excerpt: The study of materials which exhibit new and unconventional properties is of central importance for the devel- opment of advanced and refined technologies in many fields of engineering science. In this connection there has been a rapidly growing interest in real fluid effects on wave phenomena in the past few years. A prominent example is provided by Bethe-Zel'dovich-Thompson (BZT) fluids which have the distinguishing feature that they exhibit negative nonlinearity over a finite range of temperature and pressures in the pure vapour phase. However, two phase flows with and without phase change are an even richer source of new unexpected and previously thought impossible phenomena. Topics covered by this volume include waves in gases near the critical point, waves in retrograde fluids, temperature waves in superfluid helium and density waves in suspensions of particles in liquids. Clearly, the aim of the various contributions is twofold. First, they are intended to provide scientists and engineers working in these and related areas with an overview of various new physical phenomena as for example expansion shocks, sonic shocks, shock splitting, evaporation and liquafaction shocks and the experimental techniques needed to study these phenomena. Second, an attempt is made to discuss aspects of their mathematical modeling with special emphasis on properties which these phenomena have in common.
