6. heat:he at-transfer; 传热 heat 双语例句 1. heat在线翻译 1. BNi-2 brazing filler metal is widely used to braze heat-resistant alloy s by most enterprises recently in China. 目前钎焊耐热合金类材料时,大多数企业采用进口BNi-2钎料,这不仅成本较高,有时由于供货不及时而延误工期。
Fundamentals of Heat Transfer 1 IntroductionIntroductionThe term heat is defined by the first law of thermodynamics as the energy that is transported across the boundary of a thermodyna... P Stephan - VDI-Buch 被引量: 30发表: 2010年 Handbook of Vitamins and Hormones. This is a ready referenc...
Numerical predictions of three-dimensional turbulent flow and heat transfer are presented for a rotating two-pass smooth rectangular channel with channel aspect ratio of 2:1. The focus of this study is to investigate the effect of rotation, channel orientation and the sharp 180° turn on the flo...
An experimental investigation was carried out to study the effects of operating parameters on the local bed-to-wall heat transfer coefficient in a 4.5 m tall, 0.150 m diameter circulating fluidized bed with a bed temperature in the range of 65°C to 80°C, riser flow rate varying from 1400...
NMR Jafari,AT Zoughi - International Journal of Engineering - Transactions A: Basics 被引量: 3发表: 2003年 Modified on Shell and Tube Heat Exchanger Heat transfer is one of the most important processes in many industries. For this a heat exchanger is used. There are many different types of...
The heat transfer is composed of liquid film conduction and evaporation at vapor–liquid interface. The mass balance of vapor flow is considered to obtain the vapor velocity, this can evade directly solving the rarefied gas velocity field.In regard to the capillary tubes of micron scale, the ...
Performance evaluation of various nano heat transfer fluids in charging/discharging processes of an indirect solar air heating system In this study, an indirect charging/discharging solar-driven air heating system is assessed. In the chargingprocess, a nano heat transfer fluid (NHTF) is t... VM...

This paper presents local heat transfer results obtained during the condensation of Isceon 59, R407C and R404A in a smooth horizontal tube. The results have been compared with existing correlations for condensation heat transfer to assess the validity of these models for refrigerant mixtures. Two ...
