Experiments
1 Calibration of test section of a subsonic wind tunnel.
2 Smoke flow visualization on a wing model at different angles of incidence at low speeds.
3 Tuft flow visualisation on a wing model at different angles of incidences at low speeds: Identify zones of attached and separated flows
4 Surface pressure distribution around building models in multiple model arrangement
5 Surface pressure distribution on a cambered wing at different angles of incidence and calculation of lift and pressure drag.
6 Calculation of total drag of a cambered airfoil at a low incidence using pitot-static probe wake survey.
7 Measurement of typical boundary layer velocity profile on the wind tunnel wall (at low speeds) using a pitot probe and calculation of boundary layer displacement and momentum thickness in the presence of a circular cylinder model.
8 Study the effect of Blockage ratio on drag & pressure distribution of a circular cylinder.
9 Determination of turbulence level in a low speed wind tunnel.
10 Study of pressure distribution on hemispherical objects.
11 Study on internal/external flow distribution of hollow tube structure.
12 Conduct a series of test to obtain the stagnation pressure response of pitot probe in a wind tunnel for varied yaw angle and obtain the response curve in terms of error, (percentage of velocity head) to yaw angle.
