We present an analytical model of Stokes creeping flows in rectangular cavities. In the model, the fluid normal velocity at the wall is zero, while the fluid tangential velocity at the wall differs from the wall velocity. Numerical work is used to validate some of the ideas generated from this...

This paper proposes a new multistage evacuated solar distillation system that was designed to increase the productivity and improve the efficiency of the simple solar still. The solar still works by virtue of the higher evaporation rate under vacuum conditions. A mathematical model for the...

Purpose – The purpose of this paper is to clarify the relationship between automated assembly and mass production environments such as the manufacture of cars, airplanes and white goods and methods of modelling and simulation. Even in this environment high‐level automated assembly is...

The necessity of an energy supplier was to solve an impact problem presented at the damper winding ring or short-circuit ring of a 625kVA generator and to redesign a fan for it. The principal restriction was the time. It should be done in 15 calendar days, working with drawings of the machine,...

An unilateral contact problem with friction and with uncertain input data in quasi-coupled thermo-elasticity is analysed. As uncertain data coefficients of stress–strain law, coefficients of thermal conductivity, body and surface forces, thermal sources and friction coefficients are assumed,...

A finite-element method is developed to study interlaminar stress effects for the multilayered isotropic medium subjected to in-plane loads. Unilateral boundary value problem formulation is presented. Variational finite difference equations obtained from the finite-element discretization are...
