Research on dynamic shrinkage of hydraulic flushing borehole based on fractional Maxwell creep model
Meikuang AnquanHydraulic flushing and permeability improving technology has been widely used in gas extraction in soft coal seams. However, the strength of soft coal is low, so creep deformation is easy to occur, resulting in serious borehole shrinkage and thus ...

Research on pressure relief scope of hydraulic flushing bore hole
Procedia Engineering, 2011 AbstractMethods based on flow measurement and pressure measurement were employed in this paper to determine pressure relief scope of gas drainage boreholes for coal and gas outburst prevention and control. In order to measure the extent of pressure relief, the principle to choose proper sites was set up based on general gas geology features.

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT Gas generation and migration in bentonite buffer materials are critical processes affecting the performance of deep geological repositories for radioactive waste. This study presents a new hydro‐mechanical formulation for simulating gas migration in saturated, compacted bentonite, with particular emphasis on the role of non‐uniform stress ...

Neurourology and Urodynamics, EarlyView.ABSTRACT Introduction For more than four decades, the AMS‐800 has remained the clinical benchmark device for the treatment of male stress urinary incontinence (SUI). Although it remains the gold standard for male SUI, the AMS‐800 has continued to have limitations such as suboptimal post‐operative continence rates, fixed hydraulic pressure, need for ...

Polymer Composites, EarlyView.Multiscale modeling for dynamic installatioin. ABSTRACT The dynamic installation of metal interference bushings has demonstrated significant potential for improving the mechanical performance of carbon fiber‐reinforced polymer (CFRP) joints. However, the underlying mechanisms governing the remaining life enhancement remain insufficiently understood ...
