Hi there, I am an aeronautical engineer working part time to satisfy my daily needs. I have presented more than 5 international publications + 2 patent works including 3 projects. Here is my work sample
Numerical studies have been carried out using a kepsilon
turbulence model to examining the igniter characteristics and
the port geometry on flow separation, reattachment and pre-ignition
propellant surface heat flux distribution in idealized solid propellant
rocket motors with non-uniform ports. We observed through
parametric analytical studies that with the same inflow conditions
and propellant properties, heat flux histories and ignition time
sequences are different for different port geometries. We also
observed that the altered variations of the igniter characteristics will
alter the heat flux distributions and the flame spread mechanism in
solid rockets with identical port geometry. The numerical results
presented in this paper with dummy motor test run made it possible
to examining a number of factors, which are important in the ignition
transient studies of solid rocket motors with port expansion
configurations. We conjectured that more accurate description of the
gas phase to the propellant surface heat transfer process is required
for the better prediction and control of the starting transient of solid
propellant rockets with non-uniform ports.
I hope to give my best to exceed your satisfaction. thank you.
