Nearly two years ago, Chairman and CEO Jeffrey Immelt Jeffrey Immelt identified nanotechnology as one of three areas of substantial investment, citing its potential for helping develop high-heat resistant blades for gas turbine engines, more efficient MRI contrast agents, and high-strength lightweight components for a variety of products.
To date, although more advanced works have been performed to develop high performance heat exchangers with varieties of shape, size, and tube surface augmentation, heat transfer fluids with significantly improved thermal properties over those currently available remain one of the most challenging tasks.
Aiming at developing high efficiency heating system for EVs in cold regions, an ASHP system applying refrigerant injection for EVs is designed, as well as the test bench is built to investigate its performance.
In order to develop high-efficiency low-resistance heat exchangers, the heat transfer performance and further optimization of water-cooled microchannel heat sink with dimple and pin-fin were numerically studied in this work.
JH has higher SiO2 and Al2O3 content than SH, and thus if those are in amorphous state, JH may develop higher pozzolanic activity after heat treatment (Akindahunsi and Alade 2010).
A novel heat concentrator has been developed to simulate the high heat flux, by electrical heating.
The test plan for a thermo-hydraulic analysis was developed by using a high heat flux test facility, called the Korean heat load test facility by using electron beam (KoHLT-EB).
In order to develop the fabrication technology for a TBM structure, joining of FMS to FMS was developed and proved through the high heat flux (HHF) test in the previous study.
The present work will be helpful to develop more compact, higher heat transfer efficiency, lower fan power and quieter heat exchanger of refrigeration and air condition system.
Since 1902 various methods of making sapphire have been developed, but generally they use high heat and pressure to turn aluminium oxide power into crystal.
For the fabrication methods, Ferritic Martensitic Steel (FMS) to FMS and Be to FMS joinings with a Hot Isostatic Pressing (HIP) were developed and verified with a high heat flux test of up to 0.5 1.0 MW/m2.
