Modeling of the flow in a water turbine of a hydroelectric generator
The efficiency of generating units is of great economic importance to the operation of hydropower. Even a small improvement in their efficiency leads to a significant economic effect. Numerical simulation of the hydro turbine has many advantages over experimental studies. In this presentation the process of modeling the flow in a hydrоelectric generator will be outlined. Different configurations of stator and rotor blades were investigated numerically. Parameters relevant to efficiency and performance were obtained and analyzed. The focus is on a seamless workflow process in STAR-CCM+ and the...
Simulation of a vane cell oil pump
For some time now, regulated vane cell oil pumps have been used when necessary in engines for Mercedes-Benz passenger cars. This new technology requires adjustment to the established simulation methods in order to achieve optimum efficiency and operational reliability. The kinematics of vane cell pumps is based on a combination of translatory and rotary motion. The challenge for simulations lies in the substantial change in chamber volume in conjunction with a virtually incompressible fluid and complex inflow and outflow geometries. A basic requirement for these simulations is the calculation...
The InDesA Virtual Test Bench
As InDesA has specialized on the simulation and analysis of complex flow and heat transfer systems with STAR-CCM+ such as the under-hood hot soak simulation for passenger cars , it has became evident that great care had to be taken to implement auxiliary components such as heat exchangers, cooling fans and coolant pumps in order to accurately predict the overall system behavior. InDesA has therefore started to build up its Virtual Test Facility Center to investigate hydraulic and heat transfer performance of automotive auxiliary components. In the scope of this investigation auxiliary devices...
