🌬️ Wind Tunnel: Loss Budget, Contraction, Diffuser and Fan Power (2D)

Side view of an open-circuit wind tunnel with honeycomb, screens, a settling chamber, a contraction, a test section with a model, a diffuser and a fan, with moving tracer dots and a line of the total pressure falling along the tunnel. Set the test-section speed and size, the contraction ratio, the diffuser angle and area ratio, the number and openness of screens, the honeycomb length and the fan efficiency, and see the loss of each part, the fan power and the energy ratio. The contraction, the optimum diffuser angle, the pressure bookkeeping and the speed scaling are checked numerically, with four in-page numerical checks.
