Contains two papers reprinted from the Jnl. of Ind. Aerodynamics:-< 1) Wind-tunnel simulation of the adiabatic atmospheric boundary layer by roughess, barrier and mixing-device methods.< Discusses the philosophy of roughness, barrier and mixing-device simulation methods. Illustrates methods by measurements of simulations in the B.R.E.boundary layer wind tunnel. Concludes that boundary layers grown entirely naturally over a roughness fetch give the best simulations and that artificial thickening reduces the quality of the simulation.<"" 2) Determination of the model scale factor in wind-tunnel simulations of the adiabatic atmospheric boundary layer. Proposes a process for determining themodel scale factor in contemporary full-depth or part-depth simulations of the atmospheric boundary layer in a wind tunnel
