时-空守恒元解元方法作为近年来兴起的一种全新的高精度的计算方法,具有对控制方程的离散方法简单、计算精度高和通用性好等优点,是一种有广阔发展前景的数值方法。本论文应用时空守恒元和解元CE/SE方法思想,对进排气系统中的偏微分方程组的离散方程进行详细推导,并进行了实例计算,为内燃机进排气过程的数值模拟提供理论依据。
The Research on a Novel Numerical Method for Gas Exchange Process of Internal Combustion Engine
As a novel high - resolution computational method for equations of conservation law, the space- time Conservation Element and Solution Element method (CE/SE method) is a simple discrete method with these features of high accuracy and the simple construction. Based on the principles of CE/SE method, this paper deduces the discrete equations of the partial differential equation in the intake and exhaust systems and provides a theoretical basis for the numerical simulation of gas exchanging process of the internal combustion engine.
