... centers, and often unrealistic for real-time thermal analyses. In addition, it is prohibitive to use CFD for the optimization process where thousands of designs need to be generated. Floor tile airflow distribution control is a key technique for maintaining a sufficient cold air delivery to variable...

... using computational fluid dynamics (CFD)-based modeling simulations, four critical design parameters including the vortex tube radius and length, barrel radius, and the inlet width and height were optimized. NETL's open source multiphase flow with interphase exchange (MFiX) CFD code has been used...

...M. Tadjfar; Dj. Kamari An optimization study was conducted to find the optimum operational characteristics of a synthetic jet actuator (SJA) to postpone the static stall separation over an SD7003 airfoil at Reynolds number of 60,000. A genetic algorithm (GA) coupled with an artificial neural...

... 05 2013 01 09 2013 This paper presents an automatic multiobjective hydrodynamic optimization strategy for pump–turbine impellers. In the strategy, the blade shape is parameterized based on the blade loading distribution using an inverse design method. An efficient response surface model...

... design optimization Pump turbines utilize excessive energy that is available in electrical grids for pump mode operation and then produce peak energy in turbine mode at times of high demand, making them competitive in today's deregulated electricity market. According to state-of-the-art design...

...Jingchun Wu; James F. Antaki; Josiah Verkaik; Shaun Snyder; Michael Ricci Computational fluid dynamics (CFD)-based design optimization was applied to achieve the finalized design of the PediaFlow ® PF4, a magnetically levitated rotodynamic pediatric ventricular assist device. It features...

.... In the research, the valve plate geometry can be optimized by some analytical limitations to prevent the piston pressure below the vapor pressure. The limitations provide the design guide of the timings and overlap areas between valve plate ports and barrel kidneys to consider the cavitations and aerations...

...Wen-Guang Li The two-step method for optimizing net positive suction head required (NPSHr) of axial-flow pumps is proposed in this paper. First, the NPSHr at the impeller tip is optimized with impeller diameter based on experimental data of 2D cascades in available wind tunnels...
