Consider turbulent, parallel flow over an isothermal flat plate of length L, providing an average heat transfer coefficient of h_bar. The plate is divided into N smaller plates, each of length L/N.

  1. Draw a sketch
  2. State your assumptions
  3. Obtain an expression for h_bar over the entire plate of length L
  4. Obtain an expression for h_bar for the first plate of length L/N
  5. Obtain an expression for hbar over the entire plate divided by h_bar for the first plate
  6. If N = 100, how much is h_bar for the first plate divided by hbar over the entire plate

Helium at a free stream temperature of T∞ = 25°C is in parallel flow over a flat plate of length L = 3 m and temperature Ts = 85°C. However, obstacles placed in the flow intensify mixing with increasing distance x from the leading edge, and the spatial variation of temperatures measured in the boundary layer is correlated by an expression of the form T(°C) = 25 + 60 exp (−600xy), where x and y are in meters

Consider a vertical parallel-plate channel of indefinite length, with walls at different temperatures. The channel width is 2L and the wall temperatures are T1 and T2. It is assumed that T2 > T1. In this system, the heat fluxes in and out of the fluid will come into balance, yielding a thermally fully developed region with no streamwise temperature variations. With the temperature (and buoyancy) force independent of x, it is feasible to have fully developed flow. (a) Sketch the...
