Scientific Research

• Analytical • Experimental • Numerical research Numerical research “conducts” experiments on computer. It complements testing and experimentation by reducing total effort, time and cost required for experimentation and data acquisition. .

CFD is used in all stages of the engineering process: • Conceptual studies of new designs • Detailed product development • Optimization • Troubleshooting • Redesign

ANSYS FLUENT manual

CFD (Computational Fluid Dynamics) is the science of predicting fluid flow, heat and mass transfer, chemical reactions, and related phenomena.

Problem set-up: • Define material properties: fluid, solid, mixture • Appropriate physical model: turbulence,

combustion, multiphase etc. • Prescribe operating conditions • Prescribe boundary conditions • Provide initial values • Set up solver controls • Set up monitors

ANSYS Fluent

Models flow, turbulence, heat transfer, and reactions. For example, air flow over an aircraft wing, combustion in a furnace, bubble formation, blood flow, and semiconductor manufacturing.
