Characterization of Pressure Pulsation Propagation in a Pump‐Turbine Based on the Same‐Frequency Tracking Method

Energy Science &Engineering, EarlyView.
ABSTRACT Pressure pulsation is a key factor affecting the safe and stable operation of pump‐turbines. This article is based on same frequency‐tracking method on the pressure pulsation propagation characteristics of pump‐turbine during generation mode. The numerical simulation is validated by experimental study on a model pump‐turbine.

Data Centers With Direct Liquid‐Cooled Servers: Experimental Analysis and Modeling

Energy Science &Engineering, EarlyView.
Direct liquid cooling enables higher cooling temperatures in data centers, reducing cooling energy demand and enabling waste heat reuse. However, elevated coolant temperatures increase server power consumption and thermal losses to the surrounding air. A TRNSYS‐based model was developed to evaluate these effects and support energy‐efficient data center

Experimental Study on Prevention of Coal and Gas Outburst by Hydraulic Fracturing in High Gas Coal Mine in Yangquan Mining Area

Energy Science &Engineering, EarlyView.
ABSTRACT To investigate the hydraulic fracturing mechanism of high‐fluid wells in the Yangquan mining area, coal seams from the Xinyuan and Xinjing mines were selected as research subjects. Experiments were conducted using the TCQT‐III low‐permeability coalbed gas‐phase displacement and production enhancement apparatus, along with the FINESORB‐3120 ...

The State‐of‐the‐Art of Cuttings Transport Measurements

Energy Science &Engineering, EarlyView.
ABSTRACT Inadequate borehole cleaning is the primary cause of over 60% of downhole accidents in extended‐reach wells. Since the 1970s, researchers have been committed to experimental and theoretical studies on cuttings transport in extended‐reach wellbores, aiming to provide reliable experimental data and theoretical frameworks for the accurate ...
