FAQs on GATE Past Year Questions: Boundary Layer Theory - Fluid Mechanics for Mechanical Engineering
| 1. What is boundary layer theory? |  |
Ans. Boundary layer theory is a concept in fluid dynamics that explains the behavior of a thin layer of fluid near a solid surface. It provides a mathematical framework to study the transition from laminar to turbulent flow and helps in understanding the flow characteristics near boundaries.
| 2. What are the types of boundary layers? | |
Ans. There are two types of boundary layers: laminar boundary layer and turbulent boundary layer. In a laminar boundary layer, the fluid flows smoothly in parallel layers, while in a turbulent boundary layer, the fluid flows in a chaotic and irregular manner.
| 3. How is boundary layer thickness calculated? | |
Ans. The boundary layer thickness can be calculated using the momentum thickness (θ) or displacement thickness (δ). The momentum thickness is defined as the integral of the normalized velocity profile, while the displacement thickness is the integral of the difference between the actual and freestream velocity profiles.
| 4. What is the significance of the boundary layer in aerodynamics? | |
Ans. The boundary layer plays a crucial role in aerodynamics as it affects the drag, lift, and overall performance of an aircraft. Understanding the behavior of the boundary layer helps in designing efficient airfoils, reducing drag, and optimizing the performance of aircraft.
| 5. How does the boundary layer affect heat transfer? | |
Ans. The boundary layer affects heat transfer by influencing the convection process. In a laminar boundary layer, heat transfer occurs primarily by conduction, while in a turbulent boundary layer, convection becomes the dominant mode of heat transfer. The thickness and characteristics of the boundary layer determine the rate of heat transfer from a solid surface to the fluid.
