Description:
|
In this work , the effect of lubrication forces to the rotation of the eye is investigated where the eye is modeled as a perfect sphere and the movement is restricted to Listing's Law . For the lubrication forces , the nondimensional forms of Navier -Stokes and continuity equations are found , the boundary conditions are applied and the torques are derived . Then , Listing's constraint is introduced to the model and a potential function and lubrication as a damping force has been added . Using lubrication as a damping force , an optimum potential function for the model is derived . |
