Dimensional Homogeneity

Dimensional homogeneity is the condition where all terms in an equation share the same fundamental dimensions, ensuring physical correctness.

Buckingham Pi Theorem

The Buckingham Pi Theorem provides a methodology for deriving dimensionless groups in physical problems by identifying relations among variables and their dimensions.

Basic Boundary Layer Theory

This section introduces the concept of the boundary layer in fluid dynamics, detailing its characteristics, types, and significance.

Boundary Layer Concept

The boundary layer concept describes the thin region near a solid surface where fluid velocity transitions from zero to the free stream value.

Types Of Boundary Layers

This section discusses the fundamental concepts of boundary layers in fluid dynamics, focusing on laminar and turbulent boundary layers, their characteristics, and associated thicknesses.

Boundary Layer Thickness (Δ)

The boundary layer thickness (δ) represents the distance from a wall where fluid velocity reaches approximately 99% of the free stream value, which is crucial for understanding flow behaviors near surfaces.

Displacement Thickness (Δ*) And Momentum Thickness (Θ)

This section introduces displacement and momentum thickness, essential concepts in boundary layer theory that quantify the effects of the boundary layer on flow profiles.

Boundary Layer Separation

Boundary layer separation occurs when fluid near a solid surface reverses direction due to an adverse pressure gradient, impacting fluid flow characteristics.
