The study of parameters selection of model sizing appropriate for use in an Eiffel type subsonic\nboundary layer wind tunnel was investigated. Using a prototype-model dimension scale of 1:300 on a 72\nm, 20 storey prototype building with ratio 1:2:6; a width of 43.33, 83.33 mm breadth and 240 mm height\nwas produced as physical model. The result of the application of methods of global modular ratio and\narea moment for parameters selection shows that the moments of inertia obtained from the two\nmethods only differ by 2.33%. The proposed hollow rectangular configuration recommended as walls\nfor the physical model are 10.5 and 20.2 mm thick along the width and breadth, respectively. The\nassemblage of the models was rigidly bounded together by using a set of G-clamping devices and\nspecial adhesives such as epoxy resin and liquid glue. The base of the physical model was mounted on\nflat steel plate which serves as an infinitely rigid foundation resting on the polystyrene that represents\nthe soil conditions which was assumed to behave as elastic base. At the end, the model was rigidly\nfastened to the wind tunnel using solenoid wires. The original data generated for the dimensions were\nintrinsically linear and they were linearized using a natural logarithm model. Ordinary least square\nregression analysis conducted on the result show that y = 1.94 + 0.433x. The analysis of variance\n(ANOVA) is significant at P = 0.001 but the corresponding standard deviation, correlation coefficients\nand student�s T are S = 0.1561, R - Sq = 93.9% and T = 9.23, respectively. All these statistically confirm\nthat there are no serious trends to show that the proposed models are inappropriate.
