Specific heat capacity is defined as the ratio of the amount of energy that has to be transferred from one unit of mass or amount of substance to change the system temperature by one degree. However, the specific heat capacity has received very little attention for the graphene nanofluid. The...
This situation requires an integrated optimization of the energy system, which takes into account the interdependencies between heating and electricity generation. Numerous existing power system and market models have been extended and new models have been developed to assess the impact of power-to-heat...
We adopted the Debye’s idea about heat as the energy density of standing acoustic waves in elastic bodies and proposed its pseudo-relativistic implementation in the Euclidean (using the imaginary time variable) D-dimensional space-time1. Throughout this paper, the spacetime has four dimensions, ...

Heat is one of the seemingly countless forms of the quantity known as energy in physics. Energy has units of force times distance, or newton-meters, but this is usually called the joule (J). In some applications, the calorie, equal to 4.18 J, is the standard unit; in still others, th...
ISO、美标、国标都对热输入(heat input)进行了定义,不难发现,其实热输入就是一种能量,这种能量(可以是热能、也可以是其他形式的能力)施加到了焊接区域,并完成了最终焊接。 ISO 25901:heat input: energy introduced into the weld region during welding.(note Heat input is usually expressed per unit length)....
3. Energy saving and improve indoor air quality: this fresh air unit can not only introduce fresh air to improve indoor air quality, at the same time, it exchanges heat with exhaust air, which can precool for preheat fresh air, save much energy.4. Cooli...
Here, \(EK{E}_{me}=\frac{1}{2}\rho ({u}^{{\prime} 2}+{v}^{{\prime} 2})\) is the mesoscale kinetic energy per unit volume, p is the pressure, w is the vertical velocity, and Vtop (τw) is the horizontal velocity (wind stress) at the sea surface; primes and stars den...
To get a finite current one has to break the electron-hole symmetry, which is only possible when the transmission function is energy dependent. This energy dependent transmission function will act as a rectifier, which creates an asymmetry between electron and hole transport. Thus, to get a ...
