空气亥姆霍兹能方程p-ρ-T性质考察
Study on p-ρ-T properties of Helmholtz equation of state for air
【摘要】 在代表性区域内以高精度p-ρ-T性质实验数据为基础,对空气亥姆霍兹能方程与目前空分领域应用广泛的Bender方程进行了详尽的对比计算,证明了空气亥姆霍兹能方程比Bender方程具有更广泛的优越性。
【Abstract】 Based on highly precise experimental p-ρ-T data of air in representative areas,the detail comparison calculations were carried out between Helmholtz equation of state and Bender equation for air.It is confirmed that the former state equation possesses superiority over the latter one.
