Abstract:
A new method of the formulation of state equations in the area of not very big pressures is offered.
Basic parameters of the state equation are selected for complex chemical compounds using the original
version of the Simplex-method.
The method uses linear dependences of the shock wave velocity against the substance velocity and
thermal expansion data under constant pressure. For the target function a sum of quadratic differences
between calculated and experimental values has been selected. Satisfactory coincidence of theoretical
and experimental values is obtained.
Keywords:
state equation; Simplex-method; thermal expansion; shock compression.
