With the increasing heat flux at the chip and package levels, computational fluid dynamic (CFD) simulation is becoming more popular and important for estimating thermal performance of high density electronic packages. In this study, a series of similar experiments are conducted to validate the CFD numerical simulation method, and then a three-dimensional(More)
In this paper, formulated interms of vorticity, velocity and pressure, the stationary Navier-Stokes equations are discretized by stabilized finiteele mentm ethods. The method is consistent and stable for any combination of discrete vorticity, velocity and pressure spaces without requiring the B-B condition. The existence and uniqueness of the continuous and(More)
Thermal errors are the largest contributor to the dimensional errors of a workpiece in precision machining. It is very significant to study how to accurately simulate the spindle thermal errors. In this paper a novel concept of thermal error modes analysis is proposed to develop a better understanding of the thermal deformation on a machine tool. The basic(More)
