Numerical Simulates Studying In Comfortable Degree Of Air-conditioning Of Mine On Base Of CFD

According to principle of conservation,a mathematical mechanic equation of heat exchange in airflow turbulent in mine is set up in the paper. K-εequation and closed equations set are adopted, and the same time a processing method of all kinds of edge conditions is advanced. The porosity factor is introduced. The differential equation is solved by means of SIMPLE algorithm. The general CFD program PHOENICS and TECPLOT are used. The velocity field,the temperature field and the relative humidity field numerical simulation respectively. The variety regulation of the above-mentioned parameter are Analyzed and gotten.In the research,the numerical method which can reach the effective temperature is inferred,and used the effective temperature to measure the mineral environment, Make the standard of mineral environment rationalize more.
