Performance Analysis of Double-Layer Microchannel Heat Sinks under Non-Uniform Heating Conditions with Random Hotspots

Micromachines, 2017
Performance analysis of double-layer microchannel heat sinks was performed under non-uniform heating conditions having randomly distributed hotspots. Two parallel-channel (parallel-flow and counter-flow) and one cross-channel (transverse-flow) designs of

An Experimental Study of Microchannel and Micro-Pin-Fin Based On-Chip Cooling Systems with Silicon-to-Silicon Direct Bonding

Sensors, 2020
This paper describes an experimental study of the cooling capabilities of microchannel and micro-pin-fin based on-chip cooling systems. The on-chip cooling systems integrated with a micro heat sink, simulated power IC (integrated circuit) and temperature

A novel relaxation drift model for simulating liquid-vapor momentum non-equilibrium in two-phase ejectors

Case Studies in Thermal Engineering, 2023
A novel relaxation drift model (RDM) was proposed to simulate the interphase momentum non-equilibrium (slip) inside two-phase work-recovery CO2 ejectors.

Fostering Innovation: Streamlining Magnetocaloric Materials Research by Digitalization

Advanced Engineering Materials, EarlyView.
Magnetocaloric cooling (MCE) is an environmentally friendly refrigeration method with great potential. Optimizing MCE materials involves the preparation and screening of large quantities of samples, which in turn generates a large amount of data. A digitalization approach is presented that uses ontologies, knowledge graphs, and digital workflows to ...

Heat-Dissipation Performance of Nanocomposite Phase-Change Materials in a Twin-Heat-Source System

Fluids, 2020
In this paper, pure paraffin was mixed with CuO (high thermal conductivity) and Span-80 (as a dispersant). The CuO/paraffin nanocomposite phase-change materials (PCMs) were synthesized with mass fractions of 0.3%, 0.6%, and 1.2%, by a two-step method ...

The Reduction Design for Structure Borne Noise of Electronic Cabinet on Shipboard Considering Cooling Performance [PDF]

한국정밀공학회지, 2017
An air cooling system using an axial flow fan is generally applied in an electronic cabinet on shipboard. However, cases that apply a water cooling system or a mixture of water cooling and an air cooling system are gradually increased by applying the ...

Is an Apple an Orange? A Large Language Model Benchmark for Candidate Term Extraction and Subclass Decisions Against Upper Ontologies in Engineering and Materials Science

Advanced Engineering Materials, EarlyView.
Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.

Oscillating piezofan effects on natural and forced convection flow in a vertical channel with protru

Journal of Thermal Engineering
The current work investigates the flow characteristics and convective heat transfer performance of a vertically-oriented piezofan in a channel with wall-mounted protruding heat sources. A 2D numerical model is developed in COMSOL Multiphysics to simulate
