Question 1 Soalan 11 (a) For steady laminar flow of a viscous, incompressible, Newtonian fluid without free- surface effects, the equations of motion are the Continuity Equation (1) and the Navier-Stokes Equation (2): (Untuk aliran laminar mantap cecair Newtonian yang likat, tidak boleh mampat tanpa kesan permukaan bebas, persamaan gerakan adalah Persamaan Kesinambungan (1) dan Persamaan Navier-Stokes (2):1 8. V = 0 (ŰV) = 10p+v?v р ...(2) To solve these equations numerically, summarize the EIGHT steps involved in a typical CFD analysis of steady, laminar flow fields. Untuk menyelesaikan persamaan ini secara numerik, nyatakan LAPAN langkah yang terlibat dalam analisis CFD yang tipikal medan aliran mantap, laminar) (8 Marks/ Markah) (b) Suppose you are using CFD to simulate flow through a duct in which there is a circular cylinder as in Figure 1. The duct is long, but to save computer resources you choose a computational domain in the vicinity of the cylinder only. Katakan anda menggunakan CFD untuk mensimulasikan aliran melalui saluran di mana terdapat silinder bulat seperti dalam Gambarajah 1. Saluran itu panjang, tetapi untuk menjimatkan sumber komputer anda memilih domain komputasi di sekitar silinder sahaja./ Computational domain Out Figure 1 (Gambarajah 11 Explain why the downstream edge of the computational domain should be further from the cylinder than the upstream edge.
