CFD Basics: Fluid Properties

What are the key fluid properties considered in CFD simulations?

• heat capacity

• temperature

• pressure

• friction

• density, viscosity, velocity

How does density affect the behavior of fluids in CFD?

• Density only affects the color of the fluid in CFD simulations

• Higher density leads to lower flow velocity in CFD

• Density has no impact on fluid behavior in CFD

• Density affects fluid behavior by influencing flow velocity, pressure distribution, and turbulence characteristics.

Explain the significance of viscosity in CFD analysis.

• Viscosity has no impact on CFD analysis.

• Viscosity impacts the accuracy of flow simulations and plays a crucial role in capturing realistic fluid dynamics.

• Viscosity only affects the color of the fluid in simulations.

• Viscosity is only relevant in solid mechanics, not fluid dynamics.

What role does temperature play in determining fluid properties in CFD?

• Fluid properties in CFD are determined solely by pressure, not temperature
