Reacting flow modeling in STAR-CCM+
In order to meet ever challenging emission requirements while efficiency of reacting flow devices is increasing, STAR-CCM+ provides advanced reacting flow model capabilities that incorporate finite-rate chemistry and keep the computational time manageable at the same time. The models work for both, low and high-Mach number applications as well as for multi-phase flows. Examples demonstrating these capabilities will be shown. Validation of soot, NOx and CO against canonical flames using these models will also be presented. Furthermore, flexibility is provided for the users to add source terms...
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...
Not with standing the hype surrounding electric vehicles powered by expensive brushless inverter-fed machines, the commutator motor remains one of the most important of all electric machines. It powers almost all commuter trains worldwide. It is by far the most important auxiliary motor in automobiles, for fuel pumps, windscreen wipers, blowers, fans, etc. As an AC motor it is common in power tools, in washing machines, in floor-care products, and in food processing. The design of the commutator motor is a true "multi-physics" challenge. It involves not only the normal mechanical CAD, but...
