Energy saving in air conditioners is a primary concern in building projects, since a large proportion of the energy consumption in building service equipment is caused by air conditioners. The energy-saving research in air conditioners focuses mostly on the chiller system and the associated control strategies. For air conditioners in buildings, the thermal control strategy to adjust the temperature...
Oxyborate single crystals, ReCa4O(BO3)3 (Re=La, Pr, Nd, Y. Gd), have recently been demonstrated to offer superior dielectric, piezoelectric and electromechanical properties to quartz, langasite and other commonly used piezoelectric crystals. Of particular significance is the ability to function at temperatures > 1000°C, offering the potential for SAW, BAW and related sensors operational in harsh...
High intensity focused ultrasound (HIFU) tumor therapy is a new treatment technique of solid tumors and attracts interest of many researchers. In this study, a three-dimensional computational model, associated with finite difference time domain (FDTD) and Pennes Bio-heat transfer equation, is presented for studying the differences of the temperature field between self-focusing and electronic phased...
The hydrodynamic and thermal characteristics of microchannel networks are investigated by finite element analysis with commercial software Fluent. The simulation model is based on fabricated thick film LTCC substrate with 3D cooling microchannels. A comparison of the cooling performance among fractal-shaped microchannel, parallel microchannel, serpentine microchannel, spiral microchannel is also conducted...
The paper numerically investigated two thermal related problems in heat assisted magnetic recording: the dependence of the recorded mark width on the laser power and the temperature distribution and changes with time in lubricant layer at the condition without or with the heat sink layer. The results show that the mark width increases as the laser power increases and heat sink layer helps to reduce...
Single crystals in the ternary MPB PM-NPZ-PT system with relatively high TCs and ECs were fabricated by the solid-state single crystal growth (SSCG) technique and their dielectric and piezoelectric properties characterized. The dc bias effect on TRT (or the application usage temperature range), the high field unipolar strain, and the strain fatigue behavior induced by a phase change were investigated...
(1??x)[0.4BiScO3??0.6BaTiO3] + x (K1/2Bi1/2)TiO3 [BSBT-KBTx] ceramics in the perovskite solid solution system were studied for potential high temperature capacitor applications. The diectric properties of BSBT-KBTx ceramics were investigated as a function temperature and frequency. The BSBT-KBTx ceramics showed high dielectric permittivity (> 1000 @RT) and low dielectric loss over the temperature...
