Reply To: Porta's Derivation of Lempor Theory
Sorry for the delay in replying.
I think some people hold the view that the jet should “bounce” off the sides of the mixing chamber.
My thoughts on the operation of the ejector are based on Bernoulli’s theorem and the conservation of momentum. Others seem to support the “turbulent entrainment” theory. I suppose that there needs to be sufficient mixing to obtain a reasonable velocity profile in the diffuser to prevent recirculation, and this will inevitably produce some turbulence, but otherwise my view is that turbulence should be kept to a minimum.
I would be pleased to hear your views on this.
