Question

To increase the flow of through jet what should be done

Answer 1

The rate of flow of the liquid through such an orifice at a given time will depend partly on the shape, size and ... jet can be attributed to the action of a lateral force on the jet due to a change in the direction of flow velocity :-) Its purpose is to provide an increase in thrust, usually for supersonic flight, takeoff, and combat situations. Afterburning is achieved by injecting additional fuel into the jet pipe downstream of (i.e. after) the turbine.

Answer 2

2.3.6 Jet velocity

Jet velocity is not commonly used as an optimizing parameter, though some well designers do like to keep some minimum velocity across the bit nozzles. Due to pressure recovery, discussed below, the calculated jet velocities are only accurate at the throat or exit of the nozzle. If one wishes to maximize jet velocity for some reason, the simplest way is to use the minimum acceptable flow rate as an input into the bit pressure drop equation (rearranged to solve for total nozzle flow area), and the result will give maximum pressure drop across the nozzle and the corresponding maximum jet velocity.
