Research on calculation methods of simulation calculating the turbulence model in auxiliary ventilation field
Abstract：In order to study the numerical simulation results responded with the actual situation, the set of simulation parameters in the simulation software is very important. Simulation experiment, when using the model to simulate the flow field, the turbulent kinetic energy κ and turbulent kinetic energy dissipation rate ε of the value of the flow field solver results have an important impact. Different turbulent kinetic energy and turbulent kinetic energy dissipation rate calculation derived κ,ε values are different. For auxiliary ventilation air- flow, using different turbulent kinetic energy and turbulent kinetic energy dissipation rate of the results of different simulation solver. Through simulations k and three methods were used when the heading face of local ventilation flow field and compared the different methods section when the maximum wind speed, air volume calculating section results, and with the Japanese Tomita （tomita） of the test results were compared with airflow made suitable for the local turbulent kinetic energy and turbulent dissipation rate calculation. The study provides a reference value for the heading face of the flow field.
