Numerical Calculation of the Influence of Working Conditions and Rotational Speed on Pressure Pulsation of a Self‐Priming Pump

open access: yesEnergy Science &Engineering, EarlyView.
To accurately determine the pressure fluctuation characteristics of a specific self‐priming pump, a full three‐dimensional computational model was established, including the S‐tube, impeller domain, volute domain, gas‐liquid separation chamber, front and rear cavities, wear ring clearance, and reflux hole.

Innovative Dual Rotor Wind Turbine Design Based on Humpback Whale Blades: Simulation Analysis

open access: yesEnergy Science &Engineering, EarlyView.
To enhance the performance of wind turbines, this study investigates the integration of two wind energy harvesting systems. An optimal wind turbine configuration has been identified by using dual rotor wind turbine technology with a novel blade design known as the humpback blade, which is inspired by the fins of humpback whales. ABSTRACT To enhance the

A New Add‐On Flap for Performance Improvement of Small Horizontal Axis Wind Turbines

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT In the present study, two types of add‐on flaps tangential to the camber line of small horizontal axis wind turbine blade are introduced and their performances on the production power are investigated. The wind turbine of Berlin University (TU‐BERT) is used as the base turbine and the flaps' length, angle, and their locations on the blade are ...

Study on the Temporal and Spatial Evolution Mechanism of Rotating Cavitation in the First Stage Impeller of LNG Submersible Pump With Two‐Stage Splitter Blades

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT This study establishes a full‐flow passage numerical model of an LNG submerged pump equipped with two‐stage splitter blades through three‐dimensional modeling. Numerical simulations validated by liquid nitrogen experiments demonstrate that at 1.4 times the design flow rate, the peak efficiency reaches 60.6%, with a maximum head of 194.93 m ...
