Pagination or Media Count:
The governing ordinary differential equations for a lumped parameter model of a regenerative liquid gun are derived. A number of different options and assumptions are implemented. The equations are solved numerically using an efficient and robust computer code. The solutions are compared to a standard code for liquid propellant guns, and the strengths and weaknesses of each method are discussed.
