Abstract

The paper studies the natural convection of stack- driven airflow through rectangular building with Four opening. The dimensionless model of momentum and energy equations are analysed, using second order linear differential equation to develop the explicit expression for velocity, temperature profiles together with volumetric and mass- transfer by means of Laplace transform and variation of parameter method. Some numerical examples are presented graphically in order to illustrate the effects of physical parameters involved in the study. From the course of investigation, it was observed air temperature and velocity increase with the decrease in both parameters (θ0) and (Pr). While, velocity increase with the increase in both parameters (Cd) and (Gr) Respectively.

Keywords

Stack- driven forces, Natural convection flow, Rectangular building, Four openings.
