PATENT

United States Patent No. 8,453,665 B2 - Self-Acting Self-Circulating Fluid System without External Pressure Source and use in Bearing System.

• Research Focus

  My research interests are in the fields of computational fluids dynamics, thermo-fluid dynamics, combustion, and turbulence.

• Expertise

  "Numerical and experimental investigations of micro jet engines combustion chamber, thermal deburring, crystal growth reactors, centrifugal compressors, bearings, and seals.
  For numerical simulations, I used Computational Fluid Dynamics (CFD) software and wrote my own programs.
  For experimental investigations I used multiple data acquisition hardware (Texas Instruments, Neff, and TSI) with the respective software (LabView, Mozayk, and Insight) and a wide range of sensors to measure temperature, pressure, flow rate, fluid velocity, rotational velocity, strain, and relative position."
