Transverse vortex-induced vibration (VIV) of a two-dimensional, elliptic cylinder with various aspect ratios and stiffness is studied. The elastically mounted heated, the flow direction aligned thermal-induced buoyancy force. transverse VIV can be suppressed as thermal control parameter, Richardson number (Ri), increases. Complete suppression achieved when Ri above critical value, Ric. increase...

Theory and simulation results have demonstrated that four, variable speed flywheels could potentially provide the energy storage and attitude control functions of existing batteries and control moment gyros on a satellite. Past modeling and control algorithms were based on the assumption of rigidity in the flywheel’s bearings and the satellite structure. This paper provides simulation results a...
