Effect of different flue gas recirculation rates on low‐NOx combustion characteristics: A numerical simulation based on the combustion process of a gas boiler

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract NOx emissions from gas boilers severely impact the environment, and flue gas recirculation (FGR) technology can effectively reduce such emissions, yet the effects of different FGR rates on combustion performance and NOx formation remain unclear. This study thus used numerical simulation (via ANSYS Fluent, adopting the realizable k‐ε turbulence

A study of chevron type plate design on pressure drop and friction factor of brazed plate heat exchanger

Environmental Progress &Sustainable Energy, EarlyView.
Abstract Brazed plate heat exchanger (BPHE) was analyzed using computational fluid dynamics (CFD) simulations by ANSYS Fluent to investigate the chevron‐patterned plates. The influence of geometric parameters, including corrugation pitch, depth, and angle was analyzed.

Mixing Behavior of Natural Gas and Hydrogen in a High‐Efficiency Vane (HEV) Static Mixer

Energy Science &Engineering, EarlyView.
Static mixers play a crucial role in the safe transport of hydrogen‐blended natural gas. Computational fluid dynamics (CFD) was employed to investigate the effects of structural parameters of the HEV static mixer on the mixing behavior and homogeneity of natural gas and hydrogen. The modeling approach was well validated against experimental data.

Blade Count and Rotational Speed Sensitivity of Vertical‐Axis Turbines Under Guided Vehicle‐Generated Transient Wakes

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.
