Academic Work Experience:

Graduate Assistant, Tennessee Technological University Aug 2014 to Mar 2016

“Numerical and Experimental Study of Turbulent Flows around Clark Y-14 Aero foil.”

Tested a Clark Y–14 Aerofoil using AEROLAB Wind Tunnel at various Angle of Attacks and different turbulent speeds. Calculated and processed lift and drag forces on aerofoil to plot lift and drag coefficients. Generated performance curves.

Simulated the wind tunnel flows in STAR CCM+ CFD software with the help of SST k-ω Turbulence model and produced a comparative experimental and simulation study. Validated the effect of the Force Measurement Sensor on the quality of the data set generated and its effects upstream of fluid flow.

Teaching Assistant, Tennessee Technological University Jan 2015 to Dec 2015

Designed and developed experimental setups of new laboratory experiments for undergraduate mechanical students in the ME 4751 Energy Systems Labs by interacting with professors, technicians, and other teaching assistants.

Demonstrated the labs for experiments in velocity measurement, pressure measurement, heat transfer, HVAC; fan performance testing, maintained and followed Lab Safety Guidelines.

I tutor under graduate level Fluid Mechanics and Statistics to students on campus in my free time.

Projects:

Theoretical and Experimental Analysis of Evacuated U – tube Collectors for Solar Water Heating

Determined the efficiency of solar evacuated u – tube collector using water/glycol based fluid over flat plate collectors.

By using thermal analog sensor, temperature readings are noted down at both cold and warm weathers from Arduino.

All the readings are compared with ambient temperature each time in Cookeville with an average solar radiation of 4.89 kilowatt hours per square meter per day.

Numerical and Experimental analysis of Laminar flow around Circular Flat Plate

The experimental data was obtained from Aerolab open-circuit wind tunnel is compared with the simulation data from CFD.

The circular flat plate was tested at various speeds starting from 5 mph to 90 mph by changing different angle of attacks by using Model Positioning System (MPS).

For CFD solutions, Star Ccm+ was used where the geometry was created using 3-D cad and simulation was set to run after generating the mesh, defining the physics to analyze the results.

Numerical study of self – similar behavior of Turbulent flow simulation in Round jet

The statistically axis-symmetric turbulent round jet flow was simulated on a two dimensional domain at a Reynold’s number of 100,000.

For CFD solutions, Star Ccm+ was used, the fluid under consideration is air and the general work flow followed by preparing geometry, generating the mesh operations, defining the physics, defining the boundary conditions and values, setting the solving parameters and stopping criteria setting up a monitoring report and plot, running the solver until the residuals are satisfactory to prepare for analysis.

Study of Wall – bounded Turbulent flow in a Channel

The active research was studied on wall-bounded turbulent flows at high Reynolds number by considering Reynolds Stress Model (RANS) as the turbulence model.

Numerical analysis was performed for different Reynold’s numbers by using Star Ccm+ by considering air as fluid flow in the channel and for the meshing operations polyhedral mesh was used with different prism layers.

The effect of wall-grid resolution and effect of Reynolds number was studied by changing by mass-flow rate.
