Numerical Calculation and Analysis of Apply for the Heat Transfer Performance of Porous Brick

Introduces some principles and calculating method used for the problem of porous brick wall in new energy-saving area. Finite volume method is adopted to complete the numerical analysis of building blocks model. The SIMPLE algorithm is used to solve the equation of speed and pressure. Convection-diffusion subject uses second-order upwind format. Calculation mesh adopts the unstructured hexahedral style. A few examples calculated are given. The date comparisons between calculation and experiment are given up. Rectangular hole brick is affected more stronger than circle hole brick. The wall heat flux and wall temperature have been calculated. Thermal performance can be obtained through numerical calculation in the steady heat transfer, being very approximate from the experimental result. According to the calculation of temperature distribution in the brick, thermal performance can be successfully analyzed.
