Different viscous models in CFD include laminar, turbulent, and transitional models.

• Laminar model assumes flow is smooth and predictable, suitable for low Reynolds numbers.

• Turbulent model accounts for chaotic and unpredictable flow behavior, suitable for high Reynolds numbers.

• Transitional model combines aspects of both laminar and turbulent models for flows transitioning between the two.

• Examples include Spalart-Allmaras model for turbulence and SST k-omega model for transitio...read more

BS4 and BS6 are emission norms set by the government to regulate the amount of pollutants emitted by vehicles.

• BS4 stands for Bharat Stage 4 and BS6 stands for Bharat Stage 6.

• BS6 is the latest emission standard set by the government, which is more stringent than BS4.

• BS6 compliant vehicles emit lower levels of pollutants such as nitrogen oxides, carbon monoxide, hydrocarbons, and particulate matter compared to BS4 vehicles.

• BS6 compliant vehicles also have advanced technologies ...read more
