List of Experiments:

• 1. Simulation of Couette flow when the upper plate is moving with a velocity of 40 m/s. Take the distance between the plates as 4 cm. Properties of fluid are; ν = 0.000217 m2/s, ρ= 800 kg/m3. Make simulations for a pressure gradient of 0-30000 N/m2/m and 20000 N/m2/m and report the variation of velocity contours for each case.
• 2. Simulation of a channel flow (Tube flow) for a tube of diameter, 5 cm and take the fluid as water at 300C at the entry of the tube of length 0.7 m. A heat flux of 30000 W/m 2 is imposed along the wall. Obtain the contours of velocity and temperature along the length of the tube and also obtain the centre line temperature and velocity of fluid.
• 3. Simulation of a channel flow (Tube flow) for a tube of diameter, 5 cm and take the fluid as water at 300C at the entry of the tube of length 0.7 m. A constant wall temperature of 3000C is imposed along the wall. Obtain the contours of velocity and temperature along the length of the tube and also obtain the centre line temperature and velocity of fluid.
• 4. Unsteady simulation of compressible flow of air through 2D a convergent – divergent nozzle, with inlet and outlet of 0.2 m size and both are joined by a throat section where the flow area is reduced by 10% and is of sinusoidal shape. Air enters the nozzle at a pressure of 0.9 atm and leaves at 0.73 atm. Obtain the contours of velocity, pressure and Mach number.
• 5. Simulation of flow over a circular cylinder of size 5 cm for different Reynold’s number values of air and plotting the contours of velocity and vorticity.
• 6. Simulation of temperature contours for a square plate of size 0.2 m and subjected to different types of boundary conditions
• 7. Simulation of temperature contours for a pin fin subjected to natural and forced convective conditions
• 8. Simulation of Natural convection with and without radiation inside an enclosure
• 9. Simulation of Lid driven cavity problem
• 10. Structural analysis for beams and trusses
• 11. The experiments are to be conducted using ANSYS – CFX or equivalent software M.Tech, II Year, I Sem
