Determination of cavitation zone for cavitating waterjet machining using numerical simulation
FlowRecent developments of non-traditional machining techniques, like cavitating waterjet machining (CWJM), have gained attention for their simple operation and environment friendliness with zero carbon footprints. Cavitating waterjet machining leverages the

Symbolic regression modelling of the linear growth rates of stationary cross-flow instabilities
FlowAccurately predicting the growth rates of stationary cross-flow instabilities is crucial for understanding transition mechanisms in swept-wing configurations, which can significantly impact aerodynamic performance.
