The numerical simulation of temperature field and velocity field of a car room when air-condition blow hot air

近20年以来,计算流体动力学得到了飞速的发展,它被应用到了计算物理、计算化学、计算力学等多个科学计算领域,计算机技术的不断进步使得应用计算机对工程现象进行数值模拟成为可能。目前学术界和工程界解决流体和传热应用比较广泛的就是CFD技术。CFD解决问题分为前处理、求解和后处理三个步骤。本文采用CFD技术对于供暖空调车室的温度场进行数值模拟,对于车室温度场的分布均匀性做出评价,这对于汽车空调技术的研究具有非常重要的意义。

CFD has obtained the rapid development for twenty years. It has been applied to the fields of computational physics, computational chemistry, computational mechanics, and other scientific field. It is possible to numerical simulate the Engineering phenomenon with the development of computer technology. At present, CFD technology has applied widely In the science and engineering field to solve fluid and heat transfer problems. CFD solving the problem has divided into pretreatment, solving and post-processing. This paper based on the CFD technology to simulate room temperature of the heating air-condition car room and evaluate uniformity of temperature field . It has very important significance for research the car air conditioning technology.
