Book excerpt: A calculation was made for the flow and heat transfer in the turbulent free-convection boundary layer on a vertical flat plate. Formulas for the heat transfer coefficient, boundary layer thickness, and the maximum velocity in the boundary layer were obtained.

Available in PDF, EPUB and Kindle. Book excerpt: A non-local differential phenomenological theory for turbulent free-convection boundary layers along a two-dimensional heated vertical plate is described, in which both eddy viscosity and eddy thermal diffusivity are considered unknown. The total viscosity (molecular plus eddy) is taken to be governed by a parabolic rate equation which takes into account turbulent convection, diffusion, generation and decay, while the turbulent thermal diffusivity is based on a constant turbulent Prandtl number. Based on this closed system of partial differential equations, the mean velocity and temperature field as well as the eddy viscosity and the turbulent thermal diffusivity distribution can be mapped out. It is shown for the vertical-plate problem that the generation of turbulence is essentially shear induced, and that the gravity force only influences the mean velocity and temperature fields. A degenerated local theory is developed to interpret and compare with existing experimental data. Calculations show that the turbulent free-convection boundary layer consists essentially of three distinct regions, namely, the viscous sublayer, the inner layer, and the outer layer. The viscous sublayer defined by vanishing eddy viscosity, is shown to have a nonlinear velocity distribution. The inner layer is dominated by the balance of turbulent generation and decay. The outer layer is governed mainly by turbulent convection and diffusion. It is shown that Corrsin's viscous superlayer also exists in the turbulent free-convection case and that temperature fluctuations tend to reduce the sharpness of the turbulent-non-turbulent interface. It has also been found that Grashof number has strong effects on turbulent generation and decay. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Today understanding turbulence is one of the key issues in tackling flow problems in engineering. Powerful computers and numerical methods are now available for solving flow equations, but the simulation of turbulence effects, which are nearly always important in practice, are still at an early stage of development. Successful simulation of turbulence requires the understanding of the complex physical phenomena involved and suitable models for describing the turbulence momentum, heat and mass transfer. The 89 papers, including 5 invited papers, in this volume present and discuss new developments in the area of turbulence modelling and measurements, with particular emphasis on engineering-related problems. The high standard of the contributions on the developing and testing of turbulent models attests to the world-wide interest this domain is currently attracting from researchers.

This book was released on 2018-04-21 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with a natural convective heat transfer situation of significant practical importance that has not been adequately dealt with in existing texts or widely available review papers: natural convective heat transfer from horizontal and near horizontal surfaces. The aim is to provide the reader with an understanding of past studies of natural convective heat transfer from horizontal surfaces and a more detailed review of contemporary studies. The more recent work deals with heat transfer from surfaces that have more complex shapes than previously considered, with heat transfer in situations in which laminar, transitional, and turbulent flow occur; in situations where the surface is inclined at a relatively small angle to the horizontal; and in situations where there is a covering surface above the heated surface. The authors further present methods for predicting heat transfer rates in all of the situations.

This book was released on 2012-08-31 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural Convective Heat Transfer from Narrow Plates deals with a heat transfer situation that is of significant practical importance but which is not adequately dealt with in any existing textbooks or in any widely available review papers. The aim of the book is to introduce the reader to recent studies of natural convection from narrow plates including the effects of plate edge conditions, plate inclination, thermal conditions at the plate surface and interaction of the flows over adjacent plates. Both numerical and experimental studies are discussed and correlation equations based on the results of these studies are reviewed.
