Non-Dimensional Laminar Flow
Step-By-Step Ansys Fluent Non Dimensional Laminar Flow Simulation Guide
‘Step-By-Step Ansys Fluent Non Dimensional Laminar Flow Simulation Guide’ provides a practical, hands-on tutorial for setting up and solving non-dimensional laminar flow problems in Ansys Fluent. The step-by-step guide and lecture materials cover all the essential concepts, tools, and techniques required to successfully complete such simulations.
Non Dimensional Laminar Flow
Non-dimensional laminar flow refers to analyzing a laminar flow problem without specifying actual physical dimensions or units. This is done by expressing all variables in terms of reference values. Laminar flow occurs when a fluid flows in parallel layers, with no disruption between the layers. It tends to occur at low velocities.
Non Dimensional Form Benefits
Analyzing the flow in a non dimensional form has a few benefits:
- It removes dependencies on physical dimensions. The results can then be scaled and applied to different-sized systems.
- It makes the problem and results more “universal”, reducing the number of variables involved.
- It simplifies the analysis by working with dimensionless parameters instead of physical variables.
- It allows for easier validation of computational models by comparing dimensionless results to theoretical or experimental data.
To analyze a laminar flow problem in a non-dimensional form, we need to specify:
- Reference velocity: Used to normalize the actual velocity
- Reference length: Normalizes spatial dimensions
- Reference viscosity: Normalizes the dynamic viscosity
All variables in the problem are then expressed in terms of these reference values. For example:
- Non-dimensional velocity = Actual velocity / Reference velocity
- Non-dimensional length = Actual length / Reference length
This allows us to analyze the general behavior of the laminar flow, independent of the actual physical units and quantities involved. The results can then be rescaled to model flows of different sizes and speeds.
