Bengaluru, Karnataka, India

2020Responsible for developing a compact, modular and cost effective modulation circuit for Contact cooled rotary compressor.This project was hybrid of New Technology Exploration (NTI) and New Product Development (NPD).Acceptance criteria: 1. Modular in construction and suitable for 30-75kW packages2. Limitation on Number of solenoid coils to be used3. No change in compressor operation logic allowed4. reliability target of 99.5% against assured life of 40,000 Hr run time.5. No major changes ( which demands for casting changes) to be made on Inlet valve to mount modulation circuit Approach:1. Concept generation: Developed couple of concepts and shortlisted using Pugh matrix approach2. Design Validation: prepare DFMEA document and Build a proto version for checking functional test and build confidence with observation to make necessary design correction (If required)3. Detail design: Complete concept design considering the optimal way of manufacturing, suitable material selection and prepare drawings4. Supplier search: With the help of sourcing team identify suitable and reliable supplier who can meet our technical requirements and cost targets5. Endurance Test: Complete Endurance to validate the concept to meet functional requirement and reliability target numbers6. Product launch: share the final results to review team and get necessary approvals for product launch

A right beginning is important for an ameture in any field. I was lucky enough start working on one of the complex system " Centrifugal Air compressors". Responsibility:1. Assist cooling system for sizing and validation using analytical & CFD tool (Ansys CFD) and drawing creation using Creo. a. Analytical calculations for sizing water coolers for 800kW and 2000kW capacity machines b. CFD simulation for pressure drop and flow distribution study ( Geometry clean up, fluid domain creation, define boundary condition, Post process results) c. Detail drafting of coolers and review same before uploading to Windchill and release of drawings.Additional work:Validated optimal angle of Inlet guide Vanes for centrifugal machine using Analytical approach and validation of analytical results by comparing CFD results.

M.Tech Project Title: “THEORETICAL, EXPERIMENTAL AND NUMERICAL INVESTIGATIONS OF A CENTRIFUGAL BLOWER WITH FORWARD CURVE BLADES”Objective:# Understand blower performance through testing and CFD analysis # Compare manufacture blower performance data against test result# Build a robust computational model for Forward curved blower (FCB) to derive blower performance curve and validate against test dataSimulation Methodology:# 3D numerical model was built according to test setup details# Fine unstructured mesh propagation was maintained & prism meshes on blades to capture viscous effect# Mesh independent study was carried to see effect of mesh# Pressure-Pressure boundary conditions imposed to investigate the blower performance# Steady state analysis was initialized for transient to have better convergence of residualsTesting Challenges:# Blower attachment to wind tunnel# Maintain blower speed constant at all operating pressure, which is very important to plot blower performance curve# Connecting Dyno (Variable speed control motor)and blower using bellow coupling and connecting shaftCFD Simulation Challenges:# Mesh independent study was carried to see effect of mesh# Prism meshes blades to capture viscous effect# Steady state analysis was initialized for transient to have better convergence of residuals# Iterative study on various boundary conditions for inlet and outlet# Interface model frame change from frozen rotor to stage typeResult:# Validated blower test performance data against manufacturer data# Built CFD model and validated against test dataConclusion: # CFD simulation results are in good agreement with test # Equipment design which involves fan/blowers can use CFD simulation to predict the equipment performance# CFD can be very good tool for rapid new product development
