Book Description
This book presents a concise, yet thorough, reference for all heat transfer coefficient correlations and data for all types of cylinders: vertical, horizontal, and inclined. This book covers all natural convection heat transfer laws for vertical and inclined cylinders and is an excellent resource for engineers working in the area of heat transfer engineering.

Book Description
The work analyzes the natural convection of a fluid contained in an infinitely long horizontal cylinder at large Prandtl number and unit order Grashof number. The motion is generated by an imposed cosine wall temperature distribution which includes an arbitrary phase angle. This phase angle may be varied to allow for cases ranging from heating-from-the-side to heating-from-below to be investigated. From an asymptotic ordering of the governing energy and vorticity transport equations for large Prandtl number, it is shown that the core region, which contains the fluid surrounded completely by a boundary-layer flow along the cylinder wall, may assume either of two configurations. The choice of the core configuration is shown to depend upon the nature of the streamlines therein. Solutions obtained from linearized forms of the full governing equations agree with the core temperature and velocity fields which were observed experimentally for heating angles sufficiently away from the heating-from-the-side case. Also, the influence of various linearizations is studied. For heating angles near the heating-from-the-side case, a linearized form of the boundary layer equations is developed which allows the solutions to match with the second possible core configuration. The form of the results agrees generally with experimental evidence for heating-from-the-side. (Author).

Book Description
Sound and vibrations affect convective heat transfer. An oscillating flow field can induce Reynolds stresses in a boundary layer. These Reynolds stresses may affect the time-mean motion, or even be its sole cause. Solutions for convection by streaming alone have already been found, within the framework of boundary-layer analysis for a circular cylinder under transverse oscillations. Solutions are obtained here to the coupled momentum and energy boundary layer equations for the interaction of a transverse sound field with natural convection on a horizontal cylinder in terms of aximuthal series of functions of the (transformed) radial coordinate. The solutions treat the cases where the direction of oscillations, transverse to the cylinder, is either horizontal or vertical. It has been found that horizontal oscillations increase the heat transfer coefficient at the bottom of a heated cylinder, while vertical oscillations cause a decrease. (Author).
