The coupled thermal-hydraulic-mechanical behaviour of a large-scale in situ heating experiment

The thermo-hydraulic-mechanical behaviour of a large in situ heating test, the Buffer/Container Experiment (BCE), carried out at Atomic Energy of Canada’s underground research laboratory, is considered. The work can be seen as an extension of the authors’ previous research, investigating the behaviour of a large-scale test, the socalled ‘isothermal test’, to now include heating effects. Suggest...

Coupled Thermo-Hydro-Mechanical-Chemical Modeling of Water Leak-Off Process during Hydraulic Fracturing in Shale Gas Reservoirs

The water leak-off during hydraulic fracturing in shale gas reservoirs is a complicated transport behavior involving thermal (T), hydrodynamic (H), mechanical (M) and chemical (C) processes. Although many leak-off models have been published, none of the models fully coupled the transient fluid flow modeling with heat transfer, chemical-potential equilibrium and natural-fracture dilation phenome...

Dynamic Behaviour of Hydraulic Pressure Relief Valve

This paper discusses the influence of the radial clearance of the poppet of the direct spring operated pressure relief valve type DPRS06K315 on the dynamic behaviour of the valve. The mathematical model of the valve has been developed; these mathematical terms have been represented in Matlab/SIMULINK. The results obtained by a simulation describe dynamic behaviour of the valve and its influence...

Mechanical behaviour of motion for the two-dimensional monolayer system‎

‎In this paper we study the dynamics of the 2D-motion of a particle of monolayer‎. First we consider the usual physical time component and the plan manifold R2, having the polar coordinates. Then a geometric approach to nonholonomic constrained mechanical systems is applied to a problem from the two dimensional geometric dynamics of the Langmuir-Blodgett monolayer‎. We consider a constraint sub...
