numerical simulation results indicate that the finite volume method and spectral band model is suitable to deal with coupled radiation-conduction heat transfer of non-gray medium.───分析了空间多层打孔隔热材料中导热和辐射换热的复合传热问题,建立了关于反射屏的能量方程。 combined radiation and conduction...
Conduction heat transfer in gases and liquids is due to the collisions and diffusion of the molecules during their random motion. On the other hand, heat transfer in solids is due to the combination of lattice vibrations of the molecules and the energy transport by free electrons. To examine ...
located in the Paran谩 Basin - Irati Formation, was obtained through the use of the one-dimensional heat dispersion model in transient regime of finite time, in which, in the spatial variable the numerical method of finite differences (FDM) is used and in the temporal variable the Euler ...
Heat conduction through fully saturated matrices (i.e., a single-phase fluid occupying the pores), as with heat conduction through any heterogeneous media, depends on the structure of the matrix and the thermal conductivity of each phase . When the pore or particle size is smaller than the bu...

The thermal behaviour of a dielectric barrier discharge reactor is studied. The experimental tests are performed on a laboratory reactor with two working fluids: helium and air. A simple heat conduction model for calculating the heat loss is developed. By using temperature measurements in the interna...
