Download or read book A Comparison of Boundary Layer Treatments for Heat Transfer in IC Engines written by Kang Y. Huh and published by . This book was released on 1990 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three different models, the law-of-the-wall, a modified law-of-the-wall, and an approximate one-dimensional solution to the energy equation are compared for the spatially-resolved prediction of engine heat transfer. The multidimensional hydrodynamic code KIVA is used for the fluid mechanic simulation. Two different engine geometries are studied; one being a pancake-shaped chamber, and the other a bowl-in-piston geometry. Comparisons are done for a range of initial conditions of gas flow. Rates-of-pressure-rise were also varied to represent rates typical of those encountered in motored engines, and those found in fired engines. Comparisons with experimental results show that heat transfer predictions using the law-of-the-wall may be in error when source terms such as the transient, work and chemical energy terms have a significant effect in determining the temperature profile in the boundary layer. Modified wall function and approximate 1-D solution methods show some improvement for cases with low turbulence and a high rate-of-pressure-rise, where the wall function method tends to underpredict.

Available in PDF, EPUB and Kindle. Book excerpt: AI!, in the earlier conferences (Tokyo, 1986; Atlanta, 1988, Melbourne, 1991; and Hong Kong, 1992) the response to the call for presentations at ICES-95 in Hawaii has been overwhelming. A very careful screening of the extended abstracts resulted in about 500 paper being accepted for presentation. Out of these, written versions of about 480 papers reached the conference secretariat in Atlanta in time for inclusion in these proceedings. The topics covered at ICES-95 range over the broadest spectrum of computational engineering science. The editors thank the international scientific committee, for their advice and encouragement in making ICES-95 a successful scientific event. Special thanks are expressed to the International Association for Boundary Elements Methods for hosting IABEM-95 in conjunction with ICES-95. The editors here express their deepest gratitude to Ms. Stacy Morgan for her careful handling of a myriad of details of ICES-95, often times under severe time constraints. The editors hope that the readers of this proceedings will find a kaleidoscopic view of computational engineering in the year 1995, as practiced in various parts of the world. Satya N.

This book was released on 1954 with total page 654 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heat-transfer data from four wind-tunnel experiments and two free-flight experiments with turbulent boundary layers have been examined to see whether or not they are well represented by the Reynolds analogy or a modification thereof. The heat-transfer results are put into the form of dimensionless Stanton numbers based on fluid properties at the outer edge of the boundary layer and are compared with skin-friction coefficients for the same Mach numbers and wall to free-stream temperature ratios as obtained from an interpolation of the existing skin-friction data. The effective Reynolds number is taken to be the length Reynolds number measured from the effective turbulent origin, a position which differs importantly from the leading edge of the test surface in some cases.

Available in PDF, EPUB and Kindle. Book excerpt: HEAT TRANSFER BASICS Concise introduction to heat transfer, with a focus on worked example problems to aid in reader comprehension and student learning Heat Transfer Basics covers the essential topics of heat transfer in a focused manner, starting with an introduction to heat transfer that explains its relationship to thermodynamics and fluid mechanics and continuing on to key topics such as free convection, boiling and condensation, radiation, heat exchangers, and more, for an accessible and reader-friendly yet comprehensive treatment of the subject. Each chapter features multiple worked out example problems, including derivations of key governing equations and comparisons of worked solutions with computer modeled results, which helps students become familiar with the types of problems they will encounter in the field. Throughout the book, figures and diagrams liberally illustrate the concepts discussed, and practice problems allow students to test their understanding of the content. The text is accompanied by an online instructor’s manual. Heat Transfer Basics includes information on: One-dimensional, steady-state conduction, covering the plane wall, the composite wall, solid and hollow cylinders and sphere, conduction with and without internal energy generation, and conduction with constant and temperature-dependent thermal conductivity Heat transfer from extended surfaces, fins of uniform and variable cross-sectional area, fin performance, and overall fin efficiency Transient conduction, covering general lumped capacitance solution method, one- and multi-dimensional transient conduction, and the finite-difference method for solving transient problems Free and forced convection, covering hydrodynamic and thermal considerations, the energy balance, and thermal analysis and convection correlations More advanced than introductory textbooks yet not as overwhelming as textbooks targeted at specialists, Heat Transfer Basics is ideal for students in introductory and advanced heat transfer courses who do not intend to specialize in heat transfer, and is a helpful reference for advanced students and practicing engineers.
