aIt is Shell companies’ policy to promote a management style of direct involvement of employees in decisions affecting their jobs. Staff are encouraged to discuss the objectives of the unit in which they work before these are finally established. Through the staff reporting system, staffs are also...
T = T wall in ∂ΩT, (2) −k grad T ⋅ n = qwall in ∂Ωq, (3) where T is the temperature, s is the internal heat source, k is the (effective) thermal conductivity tensor, and n is the unit vector normal to and pointing outwards ∂Ω. Using the finite ...
As far as we know, there is not previous study which has used a longitudinally wavy pipe as an absorber into the parabolic trough collector unit. 展开 会议名称: SOLARPACES 2015: International Conference on Concentrating Solar Power and Chemical Energy Systems ...
PURPOSE:To obtain the heat-sensitive element with improved impedance characteristics with respect to temperature, which comprises a copolymerized polyamide, primarily composed of an undecanoamide unit and/or a dodecanoamide unit, and a specified condensed amino unit.

The launch of the advanced microwave sounding unit (AMSU) on the NOAA series of polar orbiting meteorological satellites in May 1998 has provided additional measurements. The AMSU is a microwave radiometer that can detect temperature and moisture at different levels of the atmosphere by passively ...
19.3Heat fluxmeters Heat flux(Ф) can be defined as the rate ofheat energytransfer through a given surface (W), andheat flux density(φ) is the heat flux per unit area (Wm²). Thefluxmeter, which measures this density, is called a heat fluxmeter or aheat flux sensor[14,40]. ...
