An analytical study is presented of a laminar liquid film flowing along a surface immersed in a gas stream. The results of the analysis indicate that: (1) The equilibrium film thickness is directly proportional to the square root of the liquid deposition rate; (2) the equilibrium film thickness is directly proportional to the square root of the liquid viscosity; and (3) the equilibrium film thickness is inversely proportional to the square root of the shear stress at the surface.

It was experimentally determined that the liquid boric oxide particles leaving a jet engine combustor, burning a boron-containing fuel, will have diameters of 1.0 x 10(exp -5) to 2.0 x 10(exp -5) centimeter. For this size range the particle heat-transfer and drag coefficients are essentially infinite. The results may be applied to any boron-containing fuel. Equations are developed that enable the calculation of the particle size-time history. A study of boric oxide deposition mechanisms is included, and suggestions for decreading deposition rates given.
