Analytical method for calculating a non-stationary temperature field with a variable thermal conductivity coefficient

Because of the small thermal conductivity coefficient of Ti alloy, the heat cannot disperse timely and accumulate seriously when plunge milling Ti alloy. If the cutting parameters can not be controlled well, the phenomenon of sticking will happen easily. According to the simulation and analysis of temperature field by using finite element software ABAQUS, the influence on cutting speed and feed for the Distributing of Temperature Field about Cutting Area in Plunge Milling Ti Alloy is acquired.

System effectiveness and useful life of heat pump are directly affected by whether the design of ground heat exchanger is reasonable or not. The efficiency of heat exchanger has a close relationship with soil thermal conductivity coefficient and heat diffusivity, while soil moisture content affects soil thermal conductivity coefficient and soil temperature field. In this paper, we perform numerical simulation on CFD software. Then we study the soil temperature changes through field experiment in different soil moisture content on field experiment and finally obtained the relationships of the moisture content with the single U ground soil temperature field.

The coefficient of thermal conductivity is one of the important parameters of concretes thermal performance and it has a relatively great influence on the temperature field inside its structure. This paper explores the basic equipments of the experiment on concretes coefficient of thermal conductivity and the requirements on configuration of primary materials. In the meanwhile, it studies the establishment of the model of concretes coefficient of thermal conductivity from the theoretical basis of thermal conductivity simulation, the division of thermal fluxs pathways and that of K in the formula of the coefficient of thermal conductivity.
