ABSTRACT
This chapter discusses the equation governing the statistical counting procedure for sprays and explains to a very simplified model of rocket-chamber combustion in order to obtain an estimate of the combustion efficiency. It describes the solutions to conservation equations are given for an improved model of rocket combustion and explores the heterogeneous laminar burning velocity of a spray. The chapter provides some of the more recently developed concepts in spray combustion. For solid particles, the assumption will be valid in spray combustion when either the particles are geometrically similar or their shape is of no consequence in the combustion process. In spray combustion, cases in which chemical reactions occur in the immediate neighborhood of individual particles are of particular interest. The laminar burning velocity of the spray can therefore be determined by measuring the cone angle of the flame that it produces in a steady-flow Bunsen-burner type of apparatus.
