CHAPTER ONE

1.0     INTRODUCTION

Chapter two literature review explain the various past projects that have been done about stimulation and calculation involving laminar flow in a pipe using CFDANSYS FLUENT software package.

Chapter three give details on calculation modeling where Reynolds experiment and procedure followed have been analyzed.

Chapter four gives the details about the building of Geometry, Launching of design modeler, start creation sketch on XY plane with how to Dimensioning the rectangle. More so, the project discussed the Creation of Mesh where the pipe is divided into 100 elements in the axial direction and 5 elements in the radial direction with Edge sizing the specifying the number of division.

Chapter five explained the procedure of how to set the Boundary condition with the velocity inlet and centerline boundary condition and pipe wall boundary condition.

Chapter six shows the Result presentation of velocity vector at the outlet of the pipe with velocity magnitude contours which give the rough surface at first instance but by increasing the number of contour the result gives smooth surface at the inlet, are able to show the pressure contours which is plotted on a chart so location was created along the XY axis of the pipe outlet, where we further calculate for skin friction coefficient.

Chapter seven discussed the conclusion and recommendations made based on this project

1.3     Aim and Objectives of the Project are as follows:

1.3.0  Aim

To provide student with an understanding of the principle of fluid mechanics and the numerical procedure in CFD.

1.3.1 Objectives

(1)              To understand the fundamental of viscous incompressible flows, the fundamental of compressible flow and learn the basic of non-viscous potential flows.

(2)             To be able to understand fluid dynamics principle and their application -.To be able to demonstrate competence in setting up computational fluid dynamic models, meshing, parameterization and post processing for some industrial important application. The technical competence in building and conducting CFD simulation is a skill which enhances employability.

(3)              To be formulate and solve incompressible laminar flow in a Cartesian and polar coordinates.

(4)             To be familiar with computational fluid dynamic with also demonstrate the use of ANSYS FLUENT  code for solving two-dimensional laminar and turbulent flow 

(5)             To be familiar with stream function and potential function and elementary potential flows.
