Deep Underground Science and Engineering, EarlyView.The evolution of the temperature field and frozen wall under different fracture conditions was examined by an artificial ground freezing‐based thermal‐hydraulic coupled model. It was observed that fracture inclination affects the interaction extent of freezing pipes and fracture, while phase transition extent is the dominant factor for heat transfer in

Energy Science &Engineering, EarlyView.This research explores how fluid flow, structural movement, and sound interact in an elastic baffle system. Using a numerical approach based on the finite element method, the study analyzes how noise and vibrations change with different baffle configurations. The findings reveal that shortening the baffle by half reduces noise transmission by 9%, while

Local and global low-regularity solutions to generalized Leray-alpha equations
Electronic Journal of Differential Equations, 2015 It has recently become common to study approximating equations for the Navier-Stokes equation. One of these is the Leray-alpha equation, which regularizes the Navier-Stokes equation by replacing (in most locations) the solution u with $(1-\alpha^2 ...

Energy Science &Engineering, EarlyView.Passing vehicles generate short‐duration wakes that can be redirected toward a vertical‐axis turbine. The interaction between wake structure, blade count, and rotational speed governs transient torque production. Low‐solidity configurations combined with tuned rotational speed enhance energy extraction under vehicle‐induced gusts.

Energy Science &Engineering, EarlyView.The Radial Force (RF) distribution under different cutting angles is presented in Figure 1. Generally, the distribution of RF displays divergence across different flow conditions. The pattern of force distribution reveals a total of 24 peaks, which corresponds to the number of blades of the impeller of the SCP.

An analytic model of implosion toward possible fusion
Results in Physics, 2016 We apply to a spherically symmetric system a time evolution equation from which an exact solution of the Navier–Stokes equation has been obtained (Muriel, 2011, 2014). The radial density and temperature of a gas is calculated.

Effect of Tunnel Ventilation on Hydrogen Dispersion From Leaks in Hydrogen Fuel Cell Trucks
Energy Science &Engineering, EarlyView.This study investigates hydrogen leakage scenarios involving hydrogen fuel cell trucks within tunnels. Using computational fluid dynamics methods, it explores the distribution characteristics of hydrogen concentrations and the efficiency of ventilation under different forced ventilation conditions. ABSTRACT The widespread adoption of hydrogen fuel cell

Nieuw Archief voor Wiskunde, 2013 De Navier-Stokes-vergelijkingen behoren tot de meest gebruikte vergelijkingen voor de berekening van gas- en vloeistofstromingen. Op de Vakantiecursus 2013 van het Platform Wiskunde Nederland vertelt Barry Koren over de Navier-Stokes-vergelijkingen, over stromingsleer en over openstaande millenniumproblemen.
