The Performance of Conical Diffusers Discharging through Tailpipes

Abstract

IN 1938 a review of conical diffuser performance by Patterson (Ref. 1) was published in this journal, and a reappraisal by Cockrell and Markland (Ref. 2) was given in 1963. The two articles are widely referred to for design purposes, although other reviews have appeared more recently (by Reneau et al (Ref. 3) in 1964, and Cockrell and King (Ref. 4) in 1967). Cockrell and Markland also included some preliminary results from an investigation which they instigated at Nottingham University, and it is the continuation of this work which is the subject of this paper.
