The flow of a frictional, cohesive solid through plane converging channels with Coulomb friction acting along the channel walls isinvestigated. The constitutive postulates used in the development ofthe solution are discussed and the solution is compared with those obtainedby earlier investigators. Velocity profiles, mass flow rates,and mean stress distributions along the channel walls predicted by theanalysis are compared with experimental results. The solution correctly predicts the trend of the mass flow rate as a function of thechannel opening angle as well as the magnitude of the mass flow rate interms of the flow parameters. The solution also gives an accuratemeasure of the mean stress acting along the channel walls.
The problem of predicting the size of the cavity formed belowa cylinder in the transverse flow of a frictional, cohesionless materialis investigated experimentally. A correlation which gives the lowerseparation angle as a function of the flow parameters is determined.
Finally, the temperature distribution in the wake of a heatedcylinder in the transverse flow of a granular material is investigatedexperimentally and spanwise temperature profiles are given as afunction of downstream location.
The information gained from the experimental investigation isintended to be of use in the design of heat exchanger equipment forgranular media.
