✦ Synopsis

This article presents a simple, straightforward and accurate numerical technique that can be used to predict the steady and transient temperature distributions in an annular "n with uniform cross-section. Both convection and/or thermal radiation ambient conditions are considered in this study. The heat transfer rate and "n e$ciency are also calculated. Results are compared with the exact solution for the steady case where excellent agreement was observed for an insulated tip "n and with approximate solutions for the transient case for a non-insulated tip condition.

The stability of steady-state cocurrent and countercurrent gas-liquid annular flow is considered. Transient formulation, based on the two-fluid model, results in a Kelvin-Helmholtz type ofinstability. Thus, this formulation is not suited for analyzing the steady-state stability of annular flow, sinc
