Research Interests

  • Design and develpement of an accelerometer force balance (i.e., 3 and 6-component accelerometer balances) to measure the aerodynamic forces and moments for various aerodynamic configuration within test duration of 1 ms.
  • Aerospikes ahead of the blunt body, concentrated energy deposition along the stagnation streamline and forward facing jet in the stagnation zone of a blunt body are investigated for keeping the heat load to acceptable levels.
  • Direct measurement of skin friction on backward facing step (2 mm step height) and on double-wedge model exposed to laminar hypersonic flow, using the PZT-5A piezo-ceramic gauge.
  • Effect of permanent magnetic field on the aerodynamic drag coefficient (Cd) and heat transfer rates for a 120º apex angle blunt cone configuration at Mach 8 in the IISc free piston driven hypersonic shock tunnel.
  • Using anodized aluminum pressure-sensitive paint (AA-PSP) on the truncated cone in the high supersonic tunnel of the University of Manchester at Mach 5
  • Shock tunnel testing of scaled configurations, Instrumentation and experimental gas dynamics.
