Additive Manufacturing and Solidification

The main focus of the lab is on solid-liquid phase change (melting/solidification) involving theoretical work, multiscale computational heat transfer and fluid flow modelling (CFD), microstructure modelling, stress modelling, and experiments. The various research activities are in the area of metal additive manufacturing, welding, casting, coating and thermal energy storage.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The comprehensive approach of our group, that includes development and implementation of benchmarks, validations with controlled laboratory and actual industrial-scale quantitative experiments, and process qualification, has helped to acquire advanced scientific understanding, and predictive and control capability for defects and microstructure in solidification processes. The advanced robust models have been successfully applied to various melting/solidification related manufacturing processes (additive manufacturing, welding, surface coating, casting). Further, the multi-scale physical models, engineering thermal predictors and process selection guidelines have been applied to the area of thermal energy storage (waste heat and renewable energy).
