Recent Publication(s)
  • "Investigation of swirl meter performance"

Heim DM, Ghandhi JB, Proceedings of the Institute of Mechanical Engineers Part D- Journal of Automobile Engineering 225(D8): 1067-1077 2011. The performance of vane-and impulse-type swirl meters was investigated, and a direct calibration method for swirl meters was developed.

  • "High-resolution scalar and velocity measurements in an internal combustion engine"

Petersen BR, Heim DM, Ghandhi JB, Journal of Engineering for Gas Turbines and Power-Transactions of the ASME 132(9): 092804 Sept 2010. 

  • "Residual gas homogeneity measurements"

Ghandhi JB, Bright AG, Herold RE. International Journal of Engine Research 10(23): 121-132 April 2009. Planar laser-induced fluorescence (PLIF) of a dopant added to the fuel, which was well mixed with the intake air upstream of the engine, was used to investigate inhomogeneities that arise from the incomplete mixing of the intake charge with the residual gas left in the cylinder from the previous cycle.

  • "An optimized optical system for backlit imaging"

Ghandhi JB, Heim DM. Review of Scientific Instruments 80 (5): 056105 May 2009. An optimized optical system for back-illuminated imaging was developed and was applied to automotive-type fuel injectors; the system provides significantly higher light collection efficiency than standard flood illumination. An engineered diffuser is used to distribute an extended light source through a controlled range of angles, and a field lens is used to redirect the light to the camera.

  • "Near-wall formaldehyde planar laser-induced fluorescence measurements during HCCI combustion"

Schrewe MR, Ghandhi JB, Proceedings of the Combustion Institute 31 2871-2878 Part 2 2007. The role of thermal boundary layers on homogeneous charge compression ignited engine combustion was directly evaluated by measuring the spatial profile of the formaldehyde concentration near the combustion chamber wall.
