FLUID DYNAMIC SIMULATION FOR PROPELLER Author : Tich Thien TRUONG, Eng. Duy Khuong NGUYEN, Eng. Thanh Nha NGUYEN

WHAT IS THIS DOCUMENT ABOUT? : A turbomachine is a device in which energy transfer occurs between a flowing fluid and a rotating element due to dynamic action, and results in a change in pressure and momentum of the fluid. Mechanical energy transfer occurs inside or outside of the turbomachine, usually in a steady-flow process. Turbomachines include all those machines that produce power, such as turbines, as well as those types that produce a head or pressure, such as centrifugal pumps and compressors. The turbomachine extracts energy from or imparts energy to a continuously moving stream of fluid. However in a positive displacement machine, it is intermittent. The turbomachine as described above covers a wide range of machines, such as gas turbines, steam turbines, centrifugal pumps, centrifugal and axial flow compressors, windmills, water wheels, and hydraulic turbines. In this text, we shall deal with incompressible and compressible fluid flow machines. In turbomachine problems (that its part rotates with high velocity in fluid domain), pressure, force values of fluid flow on blades are so important for design. When designers have a model of turbine blade, they want to know how it will work, specially the moment and propulsive force values supplied by it in fluid environment. More, they also want to learn the behaviour of these turbine blades in fluid for their optimal design. Normally, engineers often do many experiments with some blade models for testing. Nowadays, with the development of numerical methods and digital computer, we can simulate this kind of problem so fast and comfortably
