1. Heat pump for thermal power production in dairy farm
ABSTRACT Besides cold for milk cooling, dairy facilities need to produce hot water for cleaning of tools and equipment. Overall, ohmic heating has been used in dairy farms, increasing power consumption and manufacturing costs. Therefore, as an alternative to reduce power consumption, this paper proposed a water-water heat pumping for simultaneous cold and he

2. Construção de um sistema de aquecimento ôhmico e sua aplicação no tratamento térmico de polpa de mirtilo
O aquecimento ôhmico consiste na passagem de corrente elétrica alternada através de um alimento, transformando energia elétrica em energia térmica, promovendo, assim, um aumento de temperatura em seu interior. A habilidade desse método de gerar calor internamente no alimento permite que o aumento de temperatura seja rápido e uniforme. Essa habilidade

3. Rotating disk flow and heat transfer of a conducting non-newtonian fluid with suction-injection and ohmic heating
The steady hydromagnetic flow in a porous medium of an incompressible viscous electrically conducting non-Newtonian fluid above an infinite rotating porous disk is studied with heat transfer. An external uniform magnetic field is applied perpendicular to the disk and a uniform injection or suction is applied through the surface of the disk. Numerical solutio

4. Ignitor: physics and progress towards ignition
Thermonuclear ignition condition for deuterium-tritium plasmas can be achieved in compact, high magnetic field devices such as Ignitor. The main scientific goals, the underlying physics basis, and the most relevant engineering solutions of this experiment are described. Burning plasma conditions can be reached either with ohmic heating only or with small amo

5. Gross Thermodynamics of Heat Engines in Deep Interior of Earth
From the gross conservation laws of thermodynamics in a convecting material we derive a bound on the ratio of the rate of production of mechanical or magnetic energy to the rate of internal radioactive heating which drives the convection. Our bound for this “efficiency” depends on the temperatures in the material, and can exceed unity. Whether the bound
