Research in the field of gas explosions has had and continues to have, as its main support, physical experiments performed on various scale models, construction real size models are often large consuming materials, time labor. The rapid development computing techniques allowed among other things, transfer research virtual space, for validation computational simulations this type being still con...

characteristics of efficient roof shape is a part of configuration of efficient architecture which seems to be an ideal in contemporary architecture especially in contemporary architecture of developing countries such as iran. this study is to investigate two roof shapes in view of air flow and indoor-temperature to find efficient roofs shapes for residential buildings in tehran. computational ...
