Problem#4* - Design the optimal location of triggering flow transition to maximize the cooling efficiency of a flat plate. The boundary layer associated with parallel flow over an isothermal plate may be "tripped" at any x- location by using a fine wire that is stretched across the width of the plate. Determine the value of the critical Reynolds number Rex,c, that is associated with the optimal location of the trip wire from the leading edge that will result in maximum heat transfer from a warm plate to a cooler fluid. Assume the Nusselt number correlations provided in the text for laminar and turbulent flows apply in the laminar and turbulent regions (mixing laminar and turbulent flows, CASE C in your handout notes), respectively.
