Atomisation of liquids in hot atmospheres.

An investigation has been performed into the dynamics of thin liquid sheets. Observation by high speed photography has revealed a new mechanism of sheet instability, electrohydrodynamic in origin, when water is injected into hot combustion gases. An estimation has been made of the charge transferred to a liquid sheet from an ionised gas and a first order solution of the resulting coupled surface wave has been derived.
General first order solutions of wave-growth on finite viscosity liquid sheets have been made, while a second order solution has been obtained for the growth of inviscid sinuous waves. The results of the latter analysis have been used to satisfactorily correlate the coherent sheet length.
