This article reports a recent study on liquid cooling-based battery thermal management system (BTMS) with composite phase change material (CPCM). Both copper foam and expanded graphite were considered as the structural materials for CPCM. The behaviour of lithium-ion was experimental investigated first under different charge/discharge rates. A two-dimensional model then developed to examine performance BTMS. For foam-based CPCM modelling, an enthalpy-porosity approach applied. numerical...
This paper proposes a power system concept that integrates photovoltaic (PV) and thermoelectric (TE) technologies to harvest solar energy from wide spectral range. By introduction of the 'spectrum beam splitting' technique, short wavelength radiation is converted directly into electricity in PV cells, while long segment spectrum used produce moderate high temperature thermal energy, which then generates TE device. To overcome intermittent nature radiation, also coupled storage unit. A...
A near-field scanning is usually time-consuming to map the electromagnetic field along surface of a device. In this communication, dual probe proposed with U-shaped loop sense radio frequency (RF) magnetic and electric fields simultaneously, so that one-time by can replace two-time single-detector probes. Different from traditional using spectrum analyzer, be achieved two-output two-port vector network analyzer connecting probe. The efficient measurements on conductor-backed coplanar...
The effect of hydrogen on defects in AlGaN/GaN high-electron-mobility transistors (HEMTs) was investigated by using low-frequency noise (LFN) method. results show that drain-to-source current HEMTs after treatment is significantly larger than the fresh HEMTs. maximum variation up to 80 mA at gate-to-source voltage 0 V and 5 V. suppression collapse also observed, gate-lag characteristic becomes better for treatment. Extracted LFN method, trap density decreases about one order magnitude...
This paper develops a movable noncontact probing method of radio frequency current on printed trace based the electromagnetic induction. The measurement is validated by comparing series reconstructed periodic and pulse currents with those as known input signals microstrip line. According to our measurement, transfer impedance from under probe has linear range 10 MHz 2.2 GHz. reconstruction can be achieved even for random noise duration 1 ns single rise time 2 ns. Owing flexible relocation...
Water pollution not only aggravates the deterioration of ecological environment and endanger human health, but also has a significantly negative impact on economic growth social development. It is crucial to investigate relationship between industrial wastewater governance path reduce water pollution. In this paper, we studied whether affected using panel fixed effect model system generalized moment estimation (SYS-GMM) with data 30 provinces from 2005 2020 in China. This empirical analysis...
Combustion instabilities are frequently encountered in gas turbine engines. The main physical mechanism that leads to combustion instability is thermoacoustic coupling, where energy released as part of the process transferred into combustor acoustics, which can then affect heat release a feedback process. This paper presents an experimental study ofthis coupling for lean premixed methane―air low-swirl flame. Planar laser-induced fluorescence hydroxyl radical was employed measure behavior...
In this paper, we firstly derive the optimal strategies, including greening technology investment, production volume and order quantity decisions with stochastic demand, for emissions-dependent supply chain composed of one manufacturer retailer. Then, an advance purchase discount (APD) contract option are applied to coordinate chain. Moreover, innovative prepayment-based (PBO) is designed based on APD contract. We discuss cash flow, inventory risk allocation impacts carbon emission tax under...
