Abstract

The main objective of this work was to use desktop workstations to evaluate the computer code HEMO as a tool for predicting coronary blood flows. The flows are usually characterised by complex vortical structures and transitional effects, and as such present challenging computational problems. As the results of the computations shown in the paper demonstrate, we can predict realistic pulsatile flows in constricted tubes using the Sun Sparcstation 1+ in a matter of hours. The results shown in the paper have also demonstrated that the computer simulations can be very useful as a complementary tool for experimental investigations.

摘要

这项工作的主要目标是使用桌面工作站来评估计算机代码HEMO,将其作为预测冠状动脉血流的工具。血流通常具有复杂的涡旋结构和过渡效应,因此带来了具有挑战性的计算问题。正如本文所示的计算结果所证明的,我们可以在数小时内使用Sun Sparcstation 1+预测狭窄血管中的实际脉动血流。本文所示结果还表明,计算机模拟作为实验研究的补充工具可能非常有用。
