Need of experiments,Wind tunnel,Classification of wind tunnels,Mode of operation,Kind of test section,Applications of wind tunnels,Model making, Non-dimensional parameters,Geometric similarity,Dynamic similarity,One of the most important requirements of models is that there should be geometric similarity
between the model and the prototype. By geometric similarity it is meant that ratios of
corresponding dimensions in the model and the prototype should be the same.
Design of Low speed wind tunnel,Irregularities of flow in low speed tunnels,Reduction of turbulence,Effect of screens on turbulence,Honey combs,Wind tunnel contractions,The diffuser,Polytrophic efficiency,Isentropic efficiency,Losses in the wind tunnel circuit,Losses due to resistance in the wind tunnel circuit,Power economy,Power economy by pressurization,Objections to power economy by pressurization,Power economy by choice of working fluid,Limitations,Power economy by reduction in stagnation temperature,Reducing stagnation temperature brings down the flow temperature too. Boiling point is
