To prevent icing over wings of airplane, some heating panels are attached in the inner layers of the wing (as heat source). The heating power is required that the lowest temperature on the wing surface must exceed a critical value (below which icing may occur).
1) Establish a complete model for computational hydrodynamics and heat transfer if the flow is turbulent (using k-ε model); discuss the equation closure.
2) List all boundary conditions of (1), and, for numerical simulations of this problem, how to use wall functions?

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure

Modern high speed trains do not have perpendicular expansion gaps where rails are joined end-to-end any more they are mostly welded together but what might happen if there was a spell of particularly hot weather that causes inspection of the tracks?
