PROJECT COMPLETED:
"Optimization
of Parameters
of Rear Head Cover (RHC) 10S11 Casting Leakage from Spot Face Area using
Six-Sigma tools" at Subros Ltd, Noida.
---------------------------------------------------------------------------------------------------------------------------------------------Summary:
This project was part of Black Belt (BB) Project for six-sigma
certification from ACMA (Automotive Component Manufacturing Association)
at Subros Ltd. Our objective was to reduce the leakage in Rear Head
Cover of the 10S11 casting. This model was creating a rejection at 3200
PPM, which we aim to reduce to 1000 PPM. Leakage was found to be because
of the Blowholes in the casting and was found while checking the almost
assembled product. Therefore there was lots of cost involved in these
rejections. First of all we have selected some of the suspected
parameters, which can affect the process and then analyze through
various 6 sigma tools to ensure that they really affect or not. After
verifying the contributing parameters for the process, we go for their
improvement, so as to reduce the rejection in the process to specified
limit. We verified the data using N-Test & Hypothesis testing. We
used variable search (DOE tool) for optimization of the process.
Optimized parameters are validated using DOE tools and then implemented
on the machine under consideration. Monitoring of the process is then
done to improve process capacity.
"MultiObjective Optimization of metallurgical Tundish using Genetic Algorithm based Computational Fluid Dyamics Model" under Prof N Chakraborti at IIT Kharagpur
Summary: We made an attempt to characterize tundish of different configurations using a 3-D steady state mathematical simulation usingg CFD Technique and then optimize the simulated data. Apart from generation of flow profiles of steel inside the tundish, the residence time distribution (RTD) curves have been predicted for analysis of flow behavior inside the tundish. For the optimization of the simulated data, stress on the wall of the metallurgical tundish is to be minimized while mixing of the steel in the tundish has to be maximized, subjected to the constraints on different operating parameters. We have used Real coded predator-prey multi-objective evolutionary algorithm. I have written the code for the above algorithm and incorporate the cross-over feature of the Differential Evolution into it. Coding is done in FORTRAN 90. I analyze the result of the above algorithm for different test functions and compare it with the existing results.
" Coding and design of Computer based training for GIS (Geographical Information System) software" at Tatainfotech Limited
Summary:
Objective was to prepare a computer based training (CBT) for the user which are new to the central Ground Water Board project, along with this we also go through the basic small projects in Visual C++, which is the main platform used in central Ground Water Board Project. We used Macromedia Flash to prepare the tutorial pages. We connect these pages with database of the GWIS software. We have been given enough exposure to the SQL and Visual C++ programming.
"Genetic Algorithm for Protein Folding Simulation" at NIT Jalandhar under Dr. A K Jana
Summary:
We are focusing primarily upon the determination of structure from sequence by using Genetic Algorithm techniques. Our emphasis is also on the thermodynamics and kinetics (i.e. the detailed pathway taken by the protein to fold in nature) of the folding problem. We are also trying to envisage, how its application in Drug Design can be done. We have analyzed the protein folding problem with a simple model and potential function and compare it with the existing results. We found slight superiority of the predicted structure with our model, when compared to others. Coding is done in C++. We are further trying to extend our work to structure prediction of Crambin (a small 46 residue-size protein, from plant seed protein of cabbage crambe Abyssinica) from the simple model. The results which have been obtained so far are highly promising.

ON-GOING PROJECTS:
Optimization
of comfort level and Noise inside the Car compartment using
Computational Fluid Dynamics(CFD) model at Subros Ltd,
India.
Summary : Project involves CFD simulation
of car Air-conditioning using StarCd software. I am involved in coding
part of the project. Coding language is fortran. Simulated data has to
be optimized using Optimization tools, which has to be decided soon.
However we are working on the CFD simulation part of the project. I have
completed the grid generation using Gambit and now planning to proceed
for simulation through starCd. Project is expected to complete by March
2006. Grid generated was up to the satisfaction of our
mentor.
"Analysis of the Diesel Engine combustion chamber using CFD Techniques" under Prof Pramod S. Mehta at NIT Jalandhar
Summary: The project is related to the analysis of Computational Fluid Dynamics (CFD) simulation of the different combustion chamber geometries in terms of their flow field distribution and turbulence generation. We have used FLUENT Inc. software package for this analysis. Three-dimensional simulation is carried out for closed part of the cycle involving compression and expansion processes. The qualitative influence of different parameters concerning combustion chamber and engine operating condition as well as turbulence is discussed. This work provides a clear understanding of effect of combustion chamber geometry on in-cylinder flow field and turbulence in DI diesel engine.
