Comparison of a coupled near- and far-wake model with a free-wake vortex code [PDF]

Wind Energy Science, 2017
This paper presents the integration of a near-wake model for trailing vorticity, which is based on a prescribed-wake lifting-line model proposed by Beddoes(1987), with a blade element momentum (BEM)-based far-wake model and a 2-D shed vorticity model.

An implicit-explicit time splitting strategy for the far SOL plasma fluid model with DG-FEM discretization [PDF]

EPJ Web of Conferences
We consider a far scrape-off layer (SOL) plasma fluid model of ions that is governed by a Braginskiitype model: a one-dimensional, nonlinear system of advection-diffusion equations coupled with a diffusion equation for neutral particles.

Phase-field model of alloy solidification far from chemical equilibrium at the solid-liquid interface

Physical Review Research
We further develop a recently introduced phase-field model of far-from-equilibrium alloy solidification under additive manufacturing conditions [K. Ji et al., Phys. Rev. Lett. 130, 026203 (2023)0031-900710.1103/PhysRevLett.130.026203].

Feedforward Model Predictive Control of Fuel-Air Ratio for Lean-Burn Spark-Ignition Gasoline Engines of Passenger Cars

IEEE Access, 2019
Precise fuel-air ratio (FAR) control on transient conditions is one of the key technologies for lean-burn spark-ignition (SI) engines. To improve fuel economy and reduce emissions, lean-burn engines must regulate their FAR immediately under different ...
