Why CFD – Computational Fluid Dynamics ?
• It’s the numerical analysis method involving large computerized iterations for predicting fluid flow patterns .
• Time efficient & Optimized Solutions Process for Design Optimization
• Computerized 3D CAD model is developed – with Actual Site Drawings • High Quality Mesh is prepared for the model • After confirmation from client fluid flow simulation is proceeded to Analyze flow
patterns • Optimum of design Changes for Ideal fluid flow across the system
