Abstract :
The research analyzes distribution laws of exhaust-gas of burning liquefied-gas in closed kitchen without any kitchen hood or fan with the exergy indicator; and compares the distribution results from the exergy analysis with those from the concentration analysis. The methods are: establish the math models of exhaust-gas exergy and concentration distributions in some boundary conditions; use discrete math, digital analysis method, and PISO information regulation ways; based on a VC++ platform, use CFD-fluent software and the Tecplot Fitting software attain some distribution laws. Presents the visual exergy and concentration figures; graphs of the exhaust-gas distribution laws in the kitchen, introduces real time dynamic changes of the exhaust-gas distribution, and the flow trend of the exhaust-gas in closed kitchen without fan and the highest polluted area in the kitchen and the harm extent to the people in it. And attains the conclusions: (1) most results from exergy analysis are similar to those from the concentration; (2) exergy indicator combined the total effect factors (or potential capability to do work) together within the exhausted-gas system, to predict the pollution level in any place is more accurate; (3) most exhaust-gases are centralized at the wall that is opposite to the place where the cookware set.
