The Computational Fluid Dynamic Simulations for Gangrene Disease in Diabetic Foot

The diabetic foot is considered one of the long term diabetes complications caused by a defect in blood vessel and nerve system. This requires dealing with diabetic foot with professional medical care, so as to prevent its development in advanced stages which could end to gangrene and amputation of...
