How To Design A Bell Nozzle. Bell nozzle, and method of characteristics (moc) of a minimum length nozzle including the chamber and injectors calculations. It is an interesting question and i am afraid there is no simple answer to this question as there are many variables in it, for starters design will change with the chamber pressure, fuel used, flume profile needed, exit velocity.

• boundary layer correction of the nozzle profile is performed. W all inflection and nozzle extension. If chemical kinetics are an issue, then the acceleration of exhaust gases at the nozzle throat should be slowed by increasing the radius of curvature applied to the design
