Coupled Heat and Flow Analysis Inside a Diversion-Type Gas Heater With Vertical Guide Plate Structure

Abstract: In the natural gas heating process, the cylinder-type heater using water as an intermediate heating medium is the most extensively used. The heat exchange rate between the heating medium water and the fire and gas tubes in the great-capacity cylinder appears to be the most important element affecting a gas heater’s thermal efficiency. The water heat flow field within a new diversion-type gas heater with vertical guide plate design is described in this paper. In contrast to prior research that concentrated on n… Show more

“…Barbosa et al 31 did the study of heat transfer by means of natural convection and radiation inside two square enclosures by considering the fluid medium is semitransparent and also studied the effect of increase in Rayleigh number on average Nusselt number. Guo et al 32 simulated heat transfer by the natural convection and participating media radiation model inside a Diversion‐type gas heater by using DO radiation model. Atashafrooz et al 33 considered a complex enclosure to study the effect of radiation as the bottom wall consists of two diagonal walls and they considered that the air (semitransparent medium) inside the enclosure have 10% of (CO 2 ) and 20% of (H 2 O).…”
