If you were asked to determine a boundary layer height for a given flow at a certain location, which method would you select (approaches may be order-of-magnitude, differential, integral, etc). Describe the reasons for your selection.

Solutions

Expert Solution

Order of magnitude analysis is the simplest to solve but just give a rough estimate of the value. The differential method is a more standard approach, which reduced a 2nd order differential equation while analysing boundary layer flow. Now the solution for this differential equation is easy for simple cases like flat plate but for more complex geometry Integral method is a better approach as it is inherently more conservitive than differential method. However, the key for the success of integral method is to use a much practical velocity profile. Considering all the advantages and disadvantages the choice would be Integral approach.

In the homework, you were asked to calculate the minimum height needed for a roller coaster car to just barely make a circular loop-the-loop. Instead, suppose a roller coaster designer wants the riders to feel their seats pushing back on them with a force equal to their weight when the car is at the inside, top of the loop. What height h should the car be released from if this condition is to be met? Express your answer in terms...

Consider the two-dimensional laminar boundary layer flow of air over a wide 15 cm long flat plate whose surface temperature varies linearly from 20°C at the leading edge to 40°C at the trailing edge. This plate is placed in an airstream with a velocity of 2 m/s and a temperature of 10°C. Numerically determine how the surface heat flux varies along the plate.

The local convection coefficient on a plate decreases as the thickness of the boundary layer grows along the plate. After transition from laminar to turbulent flow, the local convection coefficient becomes much larger, even though the boundary layer is much thicker. Explain why this is so. Explain with a paragraph in a clear and straightforward manner, please.
