Approximate solution of non

The applicability of the Heat Balance Integral method (HBI) using hybrid profiles (HP n ) for heat diffusion problems in cylindrical geometry is studied. Three test problems are taken to validate the method, namely, TP1 — long hollow cylinder, inner boundary is supplied with constant heat flux and the outer boundary is at infinity, TP2 — the same geometry with the inner boundary at

Heat Conduction, 3rd Edition

The long-awaited revision of the bestseller on heat conduction Heat Conduction, Third Edition is an update of the classic text on heat conduction, replacing some of the coverage of numerical methods with content on micro- and nanoscale heat transfer. With an emphasis on the mathematics and underlying physics, this new edition has considerable depth and analytical rigor, providing a systematic

Conduction

For a problem involving cylindrical geometry, it is necessary to define a log mean cross-sectional area (A lm). (2-7) A lm A outer A inner ln A outer A inner Substituting the expression 2 p rL for area in Equation 2-7 allows the log mean area to be calculated from the inner and outer radius without first calculating the inner and outer area.

ANALYSIS OF TRANSIENT HEAT CONDUCTION IN DIFFERENT GEOMETRIES

cylindrical geometry, a number of guess temperature profiles have been assumed to obtain a generalized solution. Based on the analysis, a modified Biot number has been proposed that predicts the temperature variation irrespective the geometry of the problem.

Engineering Heat Transfer

2009/1/14Most heat transfer texts include the same material: conduction, convection, and radiation. How the material is presented, how well the author writes the explanatory and descriptive material, and the number and quality of practice problems is what makes the difference. Even more important, however, is how students receive the text. Engineering Heat Transfer, Third Edition provides a solid
