Experimental Evaluation for the Feasibility of Test Chamber in the Open-Loop Wind Tunnel
Authors: Ismail, Johanis John, Erlanda Augupta Pane, Rahman Maulana, Reza Abdu Rahman, Agri Suwandi
Abstract: The test chamber in an open-loop wind tunnel is a critical part for aerodynamic experiment. The
study aims to assess the feasibility of the new design of test chamber for open–loop wind tunnel by studying the
fluid characteristic and the average pressure in the test chamber. The study is done by a series experimental test
for the test chamber. From experimental test, the downstream velocity in the test chamber is increased from 8.9
m/s to 12.72 m/s where the pressure gradient is ranging from 6.19 to 8.398 atm with the overall turbulence
intensity for the test chamber is 0.749%. According to the results, the designed open-loop wind tunnel is
acceptable to use for an aerodynamic test
