Description of the flow problem

length of the domain: 1.8

height of the domain: 0.6

width of the domain: 0.6

diameter of the propeller: 0.45

thickness of the propeller: 0.1

inflow speed 1 at part of the left side

fixed rotational speed 1 of the propeller

outflow at part of the right and upper side

other b.c.'s: zero velocity at the fixed walls

initial condition at t=0: starting from rest

viscosity parameter: 1/nu=100


Description of the spatial discretization

coarse mesh (=level 1): 9 cells, 24 vertices, 111 d.o.f.'s

uniform refinements with exact boundary adaption

visualization on level 5: 36,864 cells, 38,769 vertices,
374,016 d.o.f.`s

computational mesh on level 6: 294,912 cells, 302,305 vertices,
2,970,624 d.o.f.`s

nonconforming nonparametric rotated trilinear fem's
(meanvalue version), UPW


Description of the temporal discretization
