10/31/2010 2 Example 8-1 3 Parallel Plates (8-2) Consider an upper plate now moving at constant velocity Application in journal bearings Small gap allows modeling as infinite parallel plates We do not need to change the governing equation Simply apply a new boundary condition 4
10/31/2010 3 Parallel Plates (8-2) The no-slip condition determines the new boundary condition Same expression from stationary plates applies (8.4) Leads to new constants and finally (8.8) Note that if U=0 we get the stationary plate expression 5 Parallel Plates (8-2) Since we have the velocity profile we can get other useful
