The Effect of Configuration on Heat Transfer and Air Flow of Ventilation Concrete Block

Abstract

This paper presents a study of heat transfer and air flow through ventilation concrete block with reverse V-shape(Ʌ) opening of different configurations, by a two dimensional numerical method. The air flow pattern was computed using the finite element method based on the standard k- turbulence model. A steady state, incompressible and turbulent flow was assumed throughout the calculation. In theory, through the consideration of two main parameters, angle (α) and air gap (h), results obtained from the model developed show a capability of providing a prototype of ventilating concrete block. In practic, the numerical method designed in the model can enhance the corporate sector, as a simulation tool supporting decision making in concrete block production.
