In this study, the transient heat transfer coefficients for helium gas flowing perpendicular (cross-flow) and parallel to a horizontal cylinder were measured. The platinum heater with a diameter of 1.0 mm or 0.7 mm and 2.0 mm was used as test heater and heated by electric current with an ...
Transient and Unsteady Heat TransferThe possibility of using drag-reducing polymer solutions in heat exchangers has been studied using a simple circular cylinder in cross flow. The cylinder was heated electrically, and Us surface temperatures monitored with thermocouples. A small flume was arranged so ...

Studies of the transient heat transfer past a circular cylinder in a steady-state viscous flow are presented for some fluid saturated fibrous porous media. Numerical results have been obtained according to the Darcy-Brinkman model by means of the finite element method. Analysis of the influence of...
The present authors believe that this representation better illustrates that heat transfer is accomplished by transient thermal interactions with microscale eddies. Although the dependence on Pr1/2 may seem unusual, it is not unique to this correlation. For example, Hughes and Duffey [23] propose a...
