Abstract: For
the calculating and simulation, it is well known that
OpenFOAM has become a very popular tool for research
work in different fields and particularly, in fluid
dynamics. But, it is also known its lack of detailed
documentation supporting solvers made using the set of
libraries provided by OpenFOAM. Among the important
technical applications about oblique shock wave,
calculation and testing base on OpenFOAM becomes very
precise and intuitive. By using one or a combination of
oblique shock waves results in more favourable
post-shock conditions (lower post-shock temperature,
etc.) when compared to utilizing a single normal shock.
In this paper, a computational study of wedge-induced
oblique shock is presented with the purpose of
understanding the fundamental gas dynamics of the waves
and their interactions. At twodimensional, time
accurate, finite-volume-based method was used to perform
the computations. The simulation was performed with
wedges of up to 37? semi-angle, with other inflow
parameters fixed. Within the computational domain of
oblique shock waves were obtained depending on the
flowMach number and the wedge semi-angle. The physical
mechanisms of these phenomena were analysed. This is the
basis for predicting the structure more dynamic flow of
reality.
