Project 01: External Aerodynamic Simulation on the Electric Scooter, Electric Minitruck, Electric Bus

Enclosures are created around the CAD model of the E-Scooter, E-Minitruck and E-Bus using space-claim (Two enclosure were created, The outer enclosure for capturing the fluid flow structure and inner enclosure to accurately capture the flow separation of fluid flow from the rear end of the vehicles).

Performed the flow analysis and grid dependency test in FLUENT and plotted the results and created contour diagrams for all the cases.

Detailed report of the significance of the drag force and point of separation at the rear end and negative pressure effect at the wake region.

Project 02: Design Optimization of Fume Capturing Hood for 100% efficiency.

Fume capturing efficiency of the hood was 60%, customer requirement was to capture 100% of fume coming from the furnace.

CAD model was toned down for easier simulation. Air domain was created around the furnace.

Natural flow simulation was achieved first and then design optimization of hood duct was done to in order to achieve 100% efficiency.

Project 03: Parametrisation of the Gate Valve

Extraction of the fluid volume from the gate valve CAD model using space-claim and performed the flow analysis inside the pipe with the gate valve.

The raise of the gate valve is parametrized and for different values of the raise the mass flow rate has been simulated.

Optimising the design of the gate valve based on the mass flow rate values of different design iteration. Project 04: Design Optimisation of Exhaust port by Conjugate Heat transfer analysis

Design and development of different variations of exhaust port for the given specifications.

Extracted the control volume from the exhaust port CAD model using Space-claim and performed the flow analysis till steady state condition is achieved.

Analysed the temperature, velocity and pressure at the different locations of the exhaust port. Project 05: Conjugate heat transfer analysis on Graphic card using Ansys Icepack.

Enclosures are created around the CAD model of graphic card in space-claim and performed the flow analysis for different mesh sizes.

Potential hot spots on the graphics card, heat transfer coefficient in those areas and the maximum temperature attained by the processor have been determined and documented. Project 06: Study on the Sloshing of lubricant inside a gear box

2D model was extracted from the gearboxes having different clearances and a code was written and loaded in Fluent in order to set the rotation to the gears.

Simulation was done for different lubricants using the dynamic meshing and best among them is determined and documented

Project 07: HVAC Optimisation of AC duct in Third and Second Tier Coaches of Indian Railways

HVAC optimization of AC duct system in a new third and second tier coaches of Indian Railways was done in order to achieve equal mass flow rate across each opening of ducts for maximum comfort of the passengers Project 08: HVAC Optimisation of AC duct in Corona Bus

Complete development of AC duct system in a Corona Bus was done in order to achieve equal mass flow rate across each opening of ducts for maximum comfort of the passengers Projects - FEA

Project 01: FEA Analysis on Missile Launcher by DRDO
