Abstract:
This paper presents a survey of original methods for solving problems of current interest
concerning numerical simulation of the dynamics of operation of a direct-acting relief valve,
as formulated and tested by Professor V. A. Tenenev, Doctor of Physics and Mathematics. New
methods (not based on experimental data) are proposed to solve the problem of selecting an initial
clearance and initial conditions for the dynamic characteristics of disk motion in a spring-loaded
relief valve. A method due to V. A. Tenenev for constructing a computational dynamical grid for
a three-dimensional analysis of the complete cycle of valve operation (“open-closed”) is presented.
Approaches and methods for reducing the dimensionality of the problem of operation of the relief
valve are discussed. Methods of taking into account the influence of the gas-dynamic feedback
on the working processes in relief valves are developed and presented. Methods, numerical
schemes and algorithms for taking into account the real properties of substances in simulating
the operation of the valve are presented.
Keywords:numerical simulation, spring-loaded direct-acting relief valve, gas dynamics, operation of the relief valve, computational schemes and algorithms
