Simulation of Heat-Exchange Processes in Coaxial Flues at Abnormally Low Temperatures
Publication: Journal of Cold Regions Engineering
Volume 31, Issue 3
Abstract
Mathematical modeling (simulation) of the movement of the air mixture in the combustion of natural gas was performed for coaxial flue tubes with countercurrent flow for conditions of extremely low ambient temperatures. Also investigated was a configuration of the flue tube in which the chimney was modified with a 45° corner cut, characterized by less icing. The calculation and analysis of 24 cases were carried out.
