Impingement/effusion cooling with low coolant mass flow.

, 2017
A potential low coolant mass flow impingement/effusion design for a low NOx combustor wall cooling application was predicted, using conjugate heat transfer (CHT) computational fluid dynamics (CFD). The effusion and impingement cooling were also predicted

Numerical study of effusion cooling on an adiabatic flat plate

Propulsion and Power Research, 2013
The present study aims to investigate the effectiveness of effusion film cooling on an adiabatic flat plate. Cylindrical holes of 30° inclination are used for supplying cold air to the hot primary flow. A non-dimensional parameter called the film cooling

The 1974 West Flank Eruption of Mount Etna: A Data-Driven Model for a Low Elevation Effusive Event

Frontiers in Earth Science, 2020
Low elevation flank eruptions represent highly hazardous events due to their location near, or in, communities. Their potentially high effusion rates can feed fast moving lava flows that enter populated areas with little time for warning or evacuation ...

Dynamic cracking properties and generating conditions of coal under rapid gas release

Deep Underground Science and Engineering, EarlyView.
Gas release tests revealed that crack initiation and propagation are jointly controlled by initial crack length, residual strength, and gas release velocity. A new outburst risk coefficient was thus developed from a fracture mechanics perspective, offering a novel predictive approach.

CFD study of effusion cooling

, 2012
The desire to increase the efficiency, i.e., reduce the\ud specific fuel consumption and raise the thrust-to-weight ratio,\ud of gas turbines has led to an increase in pressure and\ud temperature in the combustion chamber and turbine.

Advances in vital‐sign prediction and early‐warning models for underground coal mine workers integrating environmental factors

Deep Underground Science and Engineering, EarlyView.
This review synthesizes advances in predicting miners' vital signs by integrating environmental monitoring (dust, temperature, and gas) with physiological data. It highlights multi‐source data fusion techniques and early‐warning models for enhanced occupational safety in underground coal mines.

Unified Scaling Law for Lengths of Basaltic Lava Flows: Dependence on Erupted Volume and Effusion Rate

Geophysical Research Letters
Morphological scaling laws for basaltic lava flows, linking flow dimensions and eruption conditions, are essential for hazard assessment and geological analysis of basaltic eruptions.

Real‐time multiscale characterization of water migration in deep coal under stepwise pressure‐increasing injection: Combined low‐field nuclear magnetic resonance and multifractal approach

Deep Underground Science and Engineering, EarlyView.
The graphical abstract illustrates the real‐time multiscale characterization of water migration in deep coal under stepwise pressure‐increasing injection. Under in‐situ hydrostatic pressure, the water invasion front advances progressively along the axial direction as the injection pressure increases stepwise, tracked in real time by nuclear magnetic ...
