Current research interests:

•Design and performance analysis of turbomachines

•Physics of instability and its mitigation in axial compressors

•High-performance compressors: tandem rotors, contra-rotating rotors

•Effect of inflow non-uniformities (including surface roughness) on compressor performance

•Inter-component duct design and analysis

•Active/passive flow control in turbomachines

•High-performance turbomachinery for ORC and SCO2 systems

Research facilities:

Experimental: 
4 well-instrumented experimental test facilities (1.5 stage axial compressor facility, low-speed wind tunnel, cascade tunnel, contra-rotating fan test rig), surface roughness on compressor blades

Computational: 
Dedicated workstations and servers for CFD, turbomachinery-related packages, MulTall (open-source turbomachinery design code)

Facilities:

• Low speed cascade wind tunnel

  

• Exhaust annular diffuser test rig

• Low speed, low turbulence wind tunnel

• Single stage axial flow compressor rig

• Contra-rotating axial flow fan rig

                 Contra-rotating axial fans promises significant reduction in fuel burn (better efficiency)
                 Work on ducted contra-rotating fans at IIT Bombay
