3. INTRODUCTION
What is cfd ?
-Computational Fluid Dynamics .
-Historically Analytical Fluid Dynamics and EFD
(Experimental Fluid Dynamics) was used.
-CFD has become feasible due to the advent of high
speed digital computers.
-Computer simulation for prediction of fluid –flow
phenomena.

4. OBJECTIVES.
• Product design development-
product validation and enhancement.
• Design Optimization-
multi-parameter optimization.
• Flow analysis-
extensive characterization of the flow
• Performance evaluation-
performance estimation.

5. USE OF CFD.
• Why use CFD?
– Analysis and Design
• Simulation-based design instead of “build &
test”
• Simulation of physical fluid phenomena that are
difficult to be measured by experiments.
– Knowledge and exploration of flow physics

6. PROCESS.
1. Geometry description
2. Specification of flow conditions and properties
3. Selection of models
4. Specification of initial and boundary conditions
5. Grid generation and transformation
6. Specification of numerical parameters
7. Flow solution
8. Post processing: Analysis, and visualization
9. Uncertainty assessment
