The correct sequence in ascending order of the magnitude of the given parameters is momentum thickness, displacement thickness, boundary layer thickness.
Explanation:
Boundary layer thickness, momentum thickness, and displacement thickness are all parameters used to describe the behavior of fluid flow near a solid surface.
1. Boundary layer thickness:
The boundary layer is the layer of fluid that forms near a solid surface where the flow velocity is significantly affected by the presence of the surface. The boundary layer thickness is a measure of how thick this layer is. It is defined as the distance from the surface at which the flow velocity is approximately 99% of the free stream velocity. The boundary layer thickness is typically the largest of the three parameters.
2. Momentum thickness:
The momentum thickness is a measure of the amount of momentum transferred from the main flow to the boundary layer. It is defined as the integral of the velocity profile within the boundary layer, normalized by the free stream velocity. The momentum thickness represents the reduction in the thickness of the main flow due to the presence of the boundary layer. It is smaller than the boundary layer thickness.
3. Displacement thickness:
The displacement thickness is a measure of how much the flow is displaced by the presence of the boundary layer. It is defined as the integral of the velocity profile within the boundary layer, normalized by the free stream velocity. The displacement thickness represents the increase in the overall thickness of the flow due to the presence of the boundary layer. It is smaller than both the boundary layer thickness and the momentum thickness.
Based on these definitions, the correct sequence in ascending order of magnitude is momentum thickness, displacement thickness, and boundary layer thickness. This means that the momentum thickness is the smallest parameter, followed by the displacement thickness, and the boundary layer thickness is the largest parameter.
