Optimization of Pass Design of Bidirectional Thermal-Insulation Bricks

Abstract:

The thermal performance of perforated brick is affected by various factors, thermal conductivity, the holes rates, the pass design and etc. included. In order to analyze the impact of the pass design on the thermal performance of bidirectional thermal insulation bricks, the two-dimensional finite element model was developed using ANSYS. The simulated result shows that existence of vertical holes can enhance the thermal resistance in the longer dimension of the perforated brick. Under the condition of the same holes rates, narrowing the width of the vertical holes helps to improve the thermal resistance in the shorter dimension of the perforated brick. The function of these blocks are extremely influenced by the distribution of the vertical holes, the concentrated better than the both-sided when it comes to advancing the whole function.
