Unformatted text preview: EML 6154 HW 7 Due Fri. Nov. 6 th 1) Solve problem 6.3, with the following change: The boundary surface at x=0 is exposed to a timedependent incident heat flux q"(t). (Consider Eqt. 2.45a) 2) Solve problem 6.7, with following changes: Let T(x=0, y, t) = f 1 (t) Let T(x, y=b, t)= f 2 (t) Let a timedependent flux be incident be incident at x=a: q”(x=a, y, t) = f 3 (t). (You may use Eqt. 292 with no zdependence) 3) Solve problem 6.16, with the following change: Let T(r=b, , t) = f(t) (You may use Eqt. 3153) Note: dA = rdrd & dl = rd along the r=b boundary. 4) Solve problem 6.17, with the following change: Change the convective boundary condition at r=b such that the product hT oo = f 1 (t) (You may use Eqt. 4.64) 5) Two large, flat plates of a molybdenumrich alloy are to be joined together using a process called impact welding (also explosive welding). With this technique, an explosive charge is used to drive the two plates together, where the impact and resulting temperatures fuse the materials...
