CASPSP is a package of computer programs for modeling both subsonic turbulent plasma jets used in plasma spraying and behavior of spray particles in such jets. It enables to perform quickly and easily the computer estimation of the temperature and velocity distributions for a plasma jet, as well as the trajectory, velocity and thermal state of particles being sprayed, depending on the plasma spraying process parameters. This software may be useful for experts in the field of plasma spraying and for students interested in this topic.
CASPSP is a recently improved software package and its new version consists of two connected modules:
has Windows 95/NT friendly interface,
which involves the following systems for each module:
The second module is intended for computer simulation of behavior of spray particles in the plasma jet with pre-calculated distributions of the plasma temperature and velocity. The corresponding calculation program is based on the mathematical model for processes of particle heating and acceleration, which are described by the non-linear, non-stationary thermal conductivity equation and the equation of motion for a spherical particle in plasma flow with taking into account the reducing of temperature and velocity of the plasma jet due to spray powder loading. This module permits to calculate and display trajectory, velocity and temperature field for particles being sprayed, according to composition of material and initial diameter of the particles, their feed rate and conditions of their injection into the jet.
The new version of the software allows
to choose preferable units for data being inputted and outputted:
Modification of this software can be made, e.g., for simulation of various type non-transferred arc plasmatrons; for simulation of plasma jets emitted into limited space (SPS); for simulation of supersonic plasma jets and for simulation of many particles simultaneously.
