## conduction in the cylindrical geometry

### 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

### 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
