RESEARCH EXPERIENCE:
TITLE: High speed imaging of sprays using a low-cost illumination source (Sept’ 2018 to April 2019)
(As a Project Engineer at IIT Kanpur under Prof. Vaibhav Arghode PhD, University of Maryland, College Park)
Sponsoring Agency: Science and Engineering Research Board (SERB), Department of Science and Technology (DST), Govt. of India
Use of pulsed light-emitting diodes (LEDs) for illumination to obtain high contrast and high resolution images of dilute sprays.
Developing statistical and time-spectral image processing algorithms to extract droplet size distribution and other spray properties.
TITLE: Experimental investigation of liquid jet atomization in non-uniform gaseous cross-flow (Sept’ 2017 to July 2018)
(As a Project Engineer at IIT Kanpur under Prof. Vaibhav Arghode at IIT Kanpur, India)
Sponsoring Agency: SERB, DST, Govt. of India
Impact of varying liquid-to-air momentum-flux ratio was studied on the breakup characteristics of a liquid ethanol jet injected into a non-uniform cross-flow of air relevant to a reverse cross-flow combustor investigated earlier.
High-speed imaging was used to obtain primary breakup characteristics, spray centreline and outer edge trajectories to estimate penetration and dispersion.
TITLE: Experimental investigation of a liquid fuelled reverse cross-flow colorless combustor (Dec’ 2015 to Jun’ 2017)
(Master’s thesis at IIT Kanpur under Prof. Vaibhav Arghode)
A reverse cross-flow colorless combustor facility was designed and developed and operated with ethanol, both in non-premixed and premixed-prevaporized for gas turbine applications.
OH* chemiluminescence, global flame imaging and emission measurements were performed to study the effect of varying thermal loading conditions using different injection diameters on the combustor performance.
TITLE: Open loop active control of combustion noise in gas turbine combustor (Jan’ 2016 to April 2016)
(Academic project at IIT Kanpur under Prof. Kamal Poddar, PhD, UC San Diego)
A comprehensive LabVIEW code was developed to modulate the fuel flow to reduce direct combustion noise inside a laboratory scale gas turbine combustor.
Calibration of different sensors, data acquisition using NI DAQ cards and subsequent processing were thoroughly performed.
TITLE: Numerical simulation of low Reynolds number flow past two circular cylinders in Tandem (Nov’ 2014 to April 2015)
(Bachelor’s Degree project (Senior Year) at Anna University – Chennai, India under Dr. Supradeepan K., PhD, IIT-Kharagpur)
2-D incompressible finite volume Navier-Stokes solver based on Consistent Flux Reconstruction for Unstructured Grids (CFRUNS) developed by Supradeepan et al., was comprehensively studied and applied to study the 2-D flow problem past two tandem cylinders.
Vorticity contours were plotted to identify vortex shedding phenomenon.
Drag and lift coefficients were estimated and analysed for different axial spacing between the two cylinders.
