Simulation of natural ventilation of different configurations of a room equipped with a solar chimney under the city of Ouarzazate (Morocco) climatic conditions

Natural ventilation is considered as an effective way to improve and thermal comfort reduce energy consumption in residential buildings. In this sense, natural done by a solar chimney. It used increase the air flow through room converting into kinetic energy. work, we intend present results of three dimensional numerical simulation ANSYS software equipped with chimney semiarid climatic conditions Ouarzazate (Morocco). The modelled rectangular channel two South-East oriented glass faces. main objective investigate effects dimensions for fixed dimensions. We also velocity, turbulence air-flow rate each area determine optimal size.
