Inclination influences the flow patterns and thus the heat transfer during condensation in smooth tubes.However, not a lot of work has been done on diabatic two-phase flows in inclined tubes which in some previous studies have shown can significantly increases the heat transfer.

掺硼金刚石薄膜(boron doped diamond,BDD)电极因具有较高的析氧过电势、较宽的电化学窗口、较长的使用寿命、较好的稳定性受到了人们的青睐,被认为是处理有毒难生物降解有机污染物最有前景的阳极之一[1].三维多孔BDD电极的出现为BDD电极的应用、发展带来了新的契机[2].本文选择邻苯二甲酸二甲酯(DMP)作为模型有机物,研究了有机物在三维多孔BDD电极的电催化氧化性能.
掺硼金刚石薄膜电极(boron-doped diamond thin film electrode,BDD)[1]由于具有较宽的电势窗口、较低的背景电流及双电层电容、较强的耐腐蚀性、表面惰性等优点,被广泛应用于电合成、水处理、电分析、超级电容器等领域.特别是BDD电极能够产生大量羟基自由基,高效地氧化有机物,无二次污染,被认为是电催化氧化去除水中难生物降解有机污染物中最有应用前景的阳极材料[2].
The present work was conducted to investigate the air-side pressure drop and heat transfer performance of the louver fin-tube heat exchanger for automobile applications.The fourteen kinds of louver fi
Heat exchangers have been widely used in various industries.In many cases the operation conditions are rather harsh, and the corrosion of heat exchangers becomes a major problem.To solve this problem,
As long as the temperature of the exhaust stream is less than around 370℃, the thermal efficiency of the heat-to-power conversion becomes uneconomical by the employment of water-based Rankine cycle.Ac
Cryogen spray cooling (CSC) can be used in laser dermatology to prevent burning injury of skin during surgery.CSC uses a short spurt of (40 ~100 ms) on the skin surface before laser irradiation, leadi
Generally, passive perforated tiles are used in a data center and the supplied air flow rate is under-provisioned thus the balance server air requirement is met by the hot air in the room resulting in
In thermoelectric based power generation, the primary research focus has typically involved the properties of the material used in the thermoelectric material.While improving the material properties c
Presently, a significant portion of our energy is still derived from the oil and gas (ONG) industry.Until a cheaper alternate and/or near complete depletion of ONG resources, it will remain our major
The low temperature lift heat pump (LTLHP) utilizes a small difference between the condensing and evaporating temperatures of a working fluid.It requires a larger heat transfer area, a higher volume f
