Non-linear heat conduction with ramped surface heating ramp surface heating and approximate solution

Thermal Science, 2020
Non-linear heat conduction with a power-law thermal diffusivity and ramped surface temperature has been solved by the double-integration technique of the integral-balance integral method. The case of a semi-infinite medium and infinite ramp of surface temperature has been considered as example demonstrating the versatility of the solution ...

Impact of the ash deposits from coal combustion on thermal conditions of the furnace pipes [PDF]

, 2003
One of the problems of thermal power plants is the contamination of heating surfaces that arises during the boiler unit operation while combusting the solid fuel. The main part of the energy is consumed by pipes forming the furnace.

Dynamics of Magnetic Flux Elements in the Solar Photosphere [PDF]

, 1998
The interaction of magnetic fields and convection is investigated in the context of the coronal heating problem. We study the motions of photospheric magnetic elements using filtergrams obtained at the Swedish Vacuum Solar Telescope at La Palma.

Falling behavior and control effect on temperature rise under heating condition concerning water film flow on steel shutter surface

Japan Architectural Review, 2020
A series of experiments were carried out on water film flow formed by a water discharge system on the surface of steel shutters. The experiments used three types of steel shutters for fire protection.

Noise from metallic surfaces -- effects of charge diffusion [PDF]

, 2008
Non-local electrodynamic models are developed for describing metallic surfaces for a diffusive metal. The electric field noise at a distance z_0 from the surface is evaluated and compared with data from ion chips that show anomalous heating with a noise ...

Selection of floor heating by MCDA method

Budownictwo i Architektura, 2020
Using Multiple-criteria Decision Analysis (MCDA), the most favorable floor heating system of a detached house has been selected. The analysis also includes an assessment of the performance of this type of heating on small surfaces (up to 20m2).
