Low Speed Wind Tunnel
Low Speed Wind Tunnel
The first low speed (open-circuit) wind tunnel facility at the Department of Mechanical and Aerospace Engineering (LST-1@DMAE) is developed as part of the mechanical and aeronautical engineering faculties at IOE. The tunnel driven by 16 centrifugal fans each rated with output power of 500-watt can provide a maximum velocity of ~12 m/s when operated together. The test section has a cross-section of 250 mm x 250 mm with 1050mm span.
PIV Water Tank
PIV Water Tank
The water tank with dimensions 200 cm x 61 cm x 50 cm is equipped with a velocity-controlled 210cm long gantry system. 2GT 6mm belt drives the gantry head with load cell and test specimen attached along the top structure. The tank is also equipped for use with capturing and recording Particle Imaging Velocimetry (PIV) data. A class IIIB laser of output power of ~5mW, high speed camera, data acquisition (DAQ) system and opensource software system are equipped for the force measurements on models and flow measurement using PIV.
Schlieren Imaging System
Schlieren Imaging System
The z-type schlieren system has two 76mm diameter mirrors of 400mm focal length. Sony ZV-E10 Mirrorless Camera and 2.1 Chronos high speed camera compliments the experimental setup. This setup has been used on the experimental study of Mach/shock diamonds obtained from CD-nozzle, Thermal plume of flames, convective flow of preheated objects and Fluidic-Coanda (FC) nozzle with suction pipes (Su-pipes) etc.

Z-type schlieren setup including two parabolic mirrors of diameter 200 mm and focal length 1500 mm, LED light, and precision knife-edge .
High Speed Imaging
High Speed Imaging
The Chronos 2.1-HD high-speed camera supports range of applications and measurement techniques such as Vibration Analysis, Schlieren Imaging, and Particle Image Velocimetry (PIV). The 2.1Gpx/s, Full HD 1920×1080 image sensor captures 1,000 fps, and up to 24,046 fps at lower resolution.
Shock Tunnel
Shock Tunnel
The manual driven shock tube has 300 mm X 400 mm dump tank with test section of 150mm X 150mm X 200 mm. The convergent-divergent nozzle fitted in the tunnel is capable of producing exit velocity ratio of Mach 5.2.
