We have developed a continuous theory for grinding of solids in batch and continuous mills which includes only a few parameters, the values of which can be obtained directly from data on a laboratory scale batch mill. This allows an easy scale-up fro

During the First Conference of European Rheologists, which was held in Graz, Austria, in April 1982, the Provisional Committee of European Delegates to the Inter national Committee on Rheology held a meeting to discuss future European activities in

We investigate analogies between the methodology typical of the dynamics of polymeric liquids with those used in a seemingly entirely unrelated area, viz., granular flow theory and we show that the essential conceptual content of the approach is in f

The modern viewpoint which regards dimensional analysis as the basis for a theory of scaling is discussed. Several specific examples are illustrated to show how an ingenuous application of dimensional analysis and scaling may yield some very signific

The minimisation technique proposed by Binding (J. Non-Newtonian Fluid Mech., 27 (1988) 173) was used in our Generalised Engineering Bernoulli Equation framework to relate the entry pressure and stress power. We arrived at a final result similar to B

The Gaussian plume model describes the dispersion of a pollutant from a point source. The region at risk is where the concentration c exceeds a critical concentration c∗, and we call this region the critical plume. In a steady-state windless situat

A one-dimensional model is presented to study the main characteristics of magnetized fluidized beds. The Foscolo and Gibilaro particle bed model is assumed as the basis for the evaluation of the fluid-dynamic contributions to stabilization, while the

We have analysed the use of chemically reactive liquid curtains for the containment of accidental releases of phosgene. Experiments performed on absorbers with widely different diffusion times gave results which appeared to imply a different stoichio

In this work we thoroughly explore the meanings of dissipation (sometimes referred to as viscous dissipation) and stress power. To do this we utilize the Cauchy momentum equations and the first and second laws of thermodynamics. First, the generalize

Glassy polymers contain sites where excess free volume makes adsorption of gases possible; they also contain sites where ordinary absorption governed by Henry's law can occur. In this paper, we analyze the possibility of a continuous distribution of
