FREE CONVECTION IN FLUIDS HAVING A VOLUME HEAT SOURCE (Theoretical Laminar Flow Analyses for Pipe and Parallel Plate Systems)

摘要

Theoretical laminar flow analyses are given for free convection in fluids having a uniform volume heat source and for both parallel plate and cylindrical pipe geometries. The solutions are intended to he valid in the central region (vertically) of channels having small diameters and large lengths;that is, the solutions do not apply to short systems or near the ends of long systems where the velocity and temperature profiles are not yet fully established. In addition, the solutions are restricted to systems in which the long axis is vertical and in which the walls are uniformly cooled by a forced flow coolant flowing vertically upward parallel to the long axis of the system.
