โœฆ Synopsis

An analytical study is performed to demonstrate the effect of viscous dissipation on the performance of a counter-flow recuperator. Four liquids, namely, water, transformer oil, engine oil, and glycerol are selected as working fluids. It is shown that a considerable decrease in performance is obtained when the viscous frictional heating is considered. The optimum size of recuperator is found to be finite and depends on the thermal properties of the running fluids. The effect of viscous heating on the temperature variation in the recuperator is also discussed.

We consider a model of thermal dissipation for a Stefan}Boltzmann model of viscous and reactive gas in a bounded interval. We prove the existence of a global-in-time solution, and we give the asymptotic behaviour for the corresponding Dirichlet problem.

This paper studies the effect of multipath interference on the performance of random access techniques in which the power level of a packet depends on its time of arrival. The protocols considered are pure ALOHA and slotted ALOHA. Key performance measures such as channel throughout and mean packet d

The sedimentation velocity of multiparticle suspensions was investigated expetimentally for cases where the column wall is likely to have a nonnegligible effect. The experiments demonstrate that the container wall diameter influences the falling velocity only for dilute systems, which is in contrast
