Visualization experiment study on oscillatory flow characteristics of two-phase flow [PDF]

Journal of Hebei University of Science and Technology
In order to solve the oscillatory heat transfer problem of gas-liquid two-phase flow of cooling oil gallery of piston, a reciprocating oscillatory experimental device reformed by diesel engine was designed and established. The oscillatory flow process of

The Building That Teaches: Exploring Augmented Reality Affordances in Academic Incubators

Journal of Interior Design, EarlyView., 2022
ABSTRACT Efforts to enhance the experience of interior environments have led to experimentation with augmented reality (AR) technology to encourage users to participate in the built space using their mobile devices. To investigate the role of AR technologies in interior design experiences, we highlight the interdisciplinary design of a mobile AR ...

Thermal Characteristics Investigation of the Internal Combustion Engine Cooling-Combustion System Using Thermal Boundary Dynamic Coupling Method and Experimental Verification

Energies, 2018
The engine cooling system must be able to match up with the stable operating conditions so as to guarantee the engine performance. On the working cycle level, however, the dynamic thermo-state of engines has not been considered in the cooling strategy ...

Heat transfer analysis of piston cooling using nanofluids in the gallery

Micro & Nano Letters, 2015
Attaining proper temperature in engines is always a challenge for engine manufacturers primarily because temperature has a significant role in engine performance and emissions. With the development of new technology in the field of nanofluids, it seems very promising to use nanofluids as the coolant in internal combustion engines. In this reported work,

Fluid-Structure Interaction Heat Transfer of Piston with Consideration of Oil Oscillating Cooling and In-Cylinder Local Heat Transfer

Chemical Engineering Transactions, 2017
Taking the piston of heavy commercial vehicle as an example, in-cylinder local heat transfer boundary condition is obtained through the calculation of intake, spray, combustion and exhaust process; the heat transfer boundaries of the inner oil gallery ...

Spin bath maser in a cryogenically cooled sapphire whispering gallery mode resonator [PDF]

Physical Review B, 2013
We report the observation of a mechanism of maser generation in an ensemble of inter-coupled, inhomogeneously broadened two-level systems, enhanced by high quality factor electromagnetic cavity modes. In this previously unobserved form of population inversion, an inseparable quantum system leads to cavity-enhanced stimulated emission arising from ...

Spatial‐Compatibility‐Assisted Molecular Intercalation in MXenes

Advanced Materials, EarlyView.
This work demonstrates a solvent–free NH4F–mediated route for simultaneous Al removal and molecular intercalation in MXenes. Intercalants are selected by comparing their crystallographic X, Y, and Z dimensions with the MXene interlayer spacing, establishing a spatial‐compatibility criterion that rationalizes guest–host matching and enables predictive ...

Comparison of the effects on heat transfer through oil oscillation in a steel piston cooling gallery: Friction welding versus laser welding

Case Studies in Thermal Engineering
Piston cooling gallery plays a critical role in managing the temperature of the piston and its performance. This paper aims to study the effect of oscillatory heat transfer within the cooling galleries, focusing on two distinct types: flanged (friction ...

Differential Sedimentation and Cryo‐TEM Mapping Resolve Structural Heterogeneity in Conjugated Polymer Nanowires for Programmable Stretchable Electronics

Advanced Materials, EarlyView.
Density‐driven differential sedimentation fractionates solution‐assembled P3HT nanowires into crystalline and disordered constituents. High‐resolution cryo‐TEM directly visualizes the molecular chain packing within individual nanowires in real space, and recombining the fractions programs the mobility–stretchability trade‐off without chemical ...
