Hello out there! Does anyone know where I can find any books or articles on laminar coaxial jets? Specifically, coaxial nozzles used in designing chemical reactors. Any help would be greatly appreciated.

By 'coaxial' jetS, do you mean two jets: one inside another, like to mix fuel and oxidant in a rocket nozzle?

Or do you just mean one cylindrically symetric nozzle with one single jet?

Patrick,

Hi, thanks for answering my posting. By coaxial jet I mean one jet inside another. This design is used the chemical reactor to mix the carrier gas with a precursor gas in order that they will mix in the gas phase and then through a chemical reaction lay a thin film on any surface. I am interested in nozzle designs and the different combinations of nozzle inlet velocity and concentrations used in some common reactors.
