Abstract

This paper presents the design, construction, and preliminary characterization of the atmospheric boundary layer wind tunnel facility for environmental flow studies at Assiut University. The wind tunnel is a low speed-open loop and driven by a 2 kW, 4 m3/s, axial flow fan. The main core of the designed wind tunnel is the long section (3.5 m length) devoted to produce and simulate the atmospheric boundary layer (ABL) for various environmental flow studies. The simulation of the ABL can be achieved for different earth surface conditions by inserting of well designed spires arrangement and arrays of roughness elements. The design procedure and the construction steps for the main components of the wind tunnel are summarized. The experimental results of the mean axial velocity profiles for different fan speeds are presented and discussed for the preliminary characterization of the wind tunnel. The results show that the present wind tunnel is capable to maintain long run steady flow characteristics and reproducible flow patterns. The use of designed triangular spires and cube roughness elements is successful in simulating real ABL of thickness up to 600 m corresponding to urban area.
