AN ANALYSIS OF THE HEAT-TRANSFER FROM A MOVING ELLIPTIC CYLINDER

A theoretical analysis of the heat transfer from a moving elliptical c ylinder is carried out and general solutions in elliptical coordinates are obtained for aspect ratios delta, both delta > 1 and delta < 1. T he heat-flux distribution and total heat-flow rate are calculated, inv estigated for a wide range of parameters and presented graphically. Th e results obtained are useful for applications concerning thermal proc esses (laser cutting, welding, heat treatment and so on). A comparison of a moving circular cylinder with a numerical model of laser cutting is considered and discussed.
