Process Modeling
A Brief Introduction
Process Modeling and Simulation entail creating virtual representations of real-world systems to analyze and optimize their performance. Using computer algorithms and mathematical models, this approach enables the study of complex processes without physical implementation. It aids in understanding system behavior, predicting outcomes, and identifying areas for improvement. Industries like manufacturing benefit from this predictive tool to enhance efficiency, reduce costs, and accelerate innovation. By simulating various processes such as laser welding, sheet metal forming, and additive manufacuring, our industrial partners can make informed decisions, refine processes, and adapt strategies for optimal results.

Laser Metal Deposition, or Laser Additive Manufacturing, is an advanced technique depositing layers using a laser beam. Our goal is to optimize a coaxial powder nozzle for a narrower laser beam, enhancing precision in the cladding process, especially for thin walls. We redesigned an existing nozzle to focus the gas-powder stream into a narrow jet, improving deposition within the melt pool. The optimized powder nozzle, achieved through simulations and experiments, aims to elevate the effectiveness ...
Stainless steel (SS316) plates within brazed plate heat exchangers are pivotal for guiding two fluids and facilitating heat transfer. Sheet metal forming simulation enables the prediction of defects like spring back and thinning. By adjusting the forming process parameters, these issues could be minimized. Leveraging the LS Dyna finite element software in this project, the forming simulation results, validated against experimental data, exhibited an error of less than 10% in calculating spring back and thinning. ...
