CFD Simulation of In-Cylinder Flow on Different Piston Bowl Geometries in a DI Diesel Engine

Journal of Applied Fluid Mechanics, 2016
The combustion process in the diesel engine should be controlled to avoid both excessive maximum cylinder pressure and an excessive rate of pressure rise, in terms of crank angle.

Numerical studies on the flow characteristic of the marine two-stroke engine integrated with the high-pressure exhaust gas recirculation system

Case Studies in Thermal Engineering
The high-pressure exhaust gas recirculation (HP-EGR) has been well-proven for marine engines complying with the IMO Tier Ⅲ NOx regulation. Considering different turbocharged scavenging schemes and emission control modes, intake and exhaust gas management

Active Fabric Origami Enabled by Digital Embroidery of Magnetic Yarns

Advanced Materials, EarlyView.
This study demonstrates a scalable textile manufacturing process that fabricates active origami fabrics (AFO) via digital embroidery of magnetic yarns. The programmable AFO exhibits reversible 2D and 3D transformations under magnetic fields, enabling functionalities such as altering surface roughness and linear actuation.

Stiffening Liquid Crystal Elastomers with Liquid Crystal Inclusions

Advanced Materials, EarlyView.
Incorporation of low molecular weight liquid crystals (LC) into liquid crystal elastomers (LCE) leads to a significant increase in their stiffness and output work density. Such remarkable stiffening is attributed to nanoscale phase‐separation and the formation of induced‐smectic domains in polydomain and monodomain LC‐LCEs, respectively.

Reversible Phase Transitions of Anionic and Cationic Surfactant Mixtures Drive Shape Morphing Droplets

Advanced Materials, EarlyView.
A light‐controlled, reversible phase transition of ionic surfactant assemblies, coupled with dynamic partitioning between bulk phases and interfaces, induces rapid, and order‐of‐magnitude changes in oil–water interfacial tension. Surpassing the capabilities of conventional stimuli‐responsive surfactants, this transient, collaborative mechanism enables ...
