Filled Heat Efficient Ceramics

Key Engineering Materials, 2021
The increase of thermo-physical properties of masonry made of ceramic burnt products is possible through the use of heat-efficient ceramics and, in particular, porous building tiles. The use of combustible additives or foaming technology is related to increased energy costs and difficulties in obtaining products with uniformly distributed porosity.The ...

Heat Efficiency in Municipalities

Известия Российской академии наук. Энергетика, 2023
A complex analysis of heat supply systems from the standpoint of reliability, efficiency and environmental friendliness has been carried out. It has been revealed that in heat supply systems the weakest link in terms of reliability is heat networks. The main number of accidents accompanied by interruption of thermal energy supply occurs on them.

Efficiency of Brownian heat engines

Physical Review E, 1999
We study the efficiency of one-dimensional thermally driven Brownian ratchets or heat engines. We identify and compare the three basic setups characterized by the type of the connection between the Brownian particle and the two heat reservoirs: (i) simultaneous, (ii) alternating in time, and (iii) position dependent. We make a clear distinction between

Heat Exchanger Efficiency

Journal of Heat Transfer, 2006
This paper provides the solution to the problem of defining thermal efficiency for heat exchangers based on the second law of thermodynamics. It is shown that corresponding to each actual heat exchanger, there is an ideal heat exchanger that is a balanced counter-flow heat exchanger.
