The paper deals with the problem of accurate measuring techniques and experimental research methods for performance evaluation direct contact jet-type flow condensers. nominal conditions range temperature, pressure rate in all characteristic points novel test rig installation were calculated using developed model. Next, devices measurement a designed testing two-phase spray ejector condensers s...

[1] A mechanistic model is presented to describe closure of a fracture mediated by pressure solution; closure controls permeability reduction and incorporates the serial processes of dissolution at contacting asperities, interfacial diffusion, and precipitation at the free face of fractures. These processes progress over a representative contacting asperity and define compaction at the macrosco...

The sealing performance of end fittings is very important for offshore oil and gas pipelines. To investigate the sealing behavior of a ring-shaped wedge seal, global and local numerical models of the ring–pipe interaction have been developed based on the finite-element method. First, the sealing process of the ring under pressure is simulated. Second, a criterion for the penetration of fluid pr...

Accurate information on heat transfer and temperature distribution in metal foams is necessary for design and modelling of thermal-hydraulic systems incorporating metal foams. The analysis of heat transfer requires determination of the effective thermal conductivity as well as the thermal contact resistance (TCR) associated with the interface between the metal foam and the adjacent surfaces/lay...

the vehicle braking system is considered to be one of the most fundamental safety-critical systems in modern vehicles, as its main purpose is to stop or decelerate the vehicle. the frictional heat generated during braking application can cause numerous negative effects on the brake assembly, such as brake fade, premature wear, thermal cracks and disc thickness variation. in the past, surface ro...

This study numerically obtains the thermal elastohydrodynamic lubrication (TEHL) solutions of different physical-property models five lubricants and properties solids. The solution was computed at nominal line contact for both Newtonian non-Newtonian fluids. density, viscosity, specific heat, conductivity were considered functions temperature pressure, whereas expansivity a function pressure. l...
