Computational Fluid Dynamics or CFD is the analysis of systems involving fluid flow, heat transfer and associated phenomena such as chemical reactions by means of computer based simulation.
*A tool for solving PDE’s
*3 fundamental principles:
Mass is conserved (Continuity equation);
Newton’s second law ( Navier- Stokes Equation);
Energy is conserved (Bernoulli’s Equation
Advantages of CFD
*It complements experimental and theoretical fluid dynamics by providing an alternative cost effective means of simulating real flows.
Better visualization and enhanced understanding of designs.
Testing many variations until you arrive at an optimal result before physical prototyping and testing. Practically unlimited level of detail of results at virtually no added expense.
Compression of design and development cycle.
