| الوصف: | 90 This thesis is an application of finite element analysis, the goal is to discuss the influence of the mesh, and build a computer model for Saybolt viscosity measurement. At first, we will introduce the method to measure the Saybolt viscosity and the transform between the Saybolt viscosity, kinematic viscosity, and absolute viscosity. And we will point out the model we build, and the difference between our model and real condition. In this paper, we use 2-D incompressible steady-state Navier-Stokes equations as the base function to solve our problem. Secondly, will discuss the method we used — the penalty method. Besides, introduce some basic theory of finite element method, and use some tips to simplify the problem we met. And then, an introduction is given on conjugate gradient method we use to iterate the variation of system. Finally, we will discuss some fluid problems and the advantage or disadvantage present in our computer model, and compare with the real condition. |
