CALCULATION OF TEMPERATURE-HUMIDITY MODE OF BRICK AND REINFORCED CONCRETE CHIMNEYS WALLS

open access: yesИзвестия высших учебных заведений: Проблемы энергетики, 2018
The method for calculating the temperature-humidity mode of brick and reinforced concrete chimneys is presented. The processes of heat exchange of combustion products in the gas volume of the chimneys and heat and mass transfer in it’s walls also, are ...

Thermodynamic factor and vacuum crystallization

open access: yesFoods and Raw Materials, 2022
Sucrose crystallization depends on various thermal phenomena, which makes them an important scientific issue for the sugar industry. However, the rationale and theory of sucrose crystallization still remain understudied.

Feshbach-Einstein Condensates [PDF]

open access: yesPhysical Review Letters, 2009
We investigate the phase diagram of a two-species Bose-Hubbard model describing atoms and molecules on a lattice, interacting via a Feshbach resonance. We identify a region where the system exhibits an exotic super-Mott phase and regions with phases characterized by atomic and/or molecular condensates.

Binary liquid film condensation from water-ammonia vapors mixture flowing downward along a parallel plate condenser

open access: yesFrontiers in Mechanical Engineering, 2023
The ammonia-water film condensation is used as an efficient working fluid in industrial applications such as refrigeration, plate condenser and evaporator, absorber/generator heat exchange, air-conditioning, heat pumps and separation processes.

Physics of $\pi$-Meson Condensation and High Temperature Cuprate Superconductors

open access: yes, 2009
The idea of condensation of the Goldstone $\pi$-meson field in nuclear matter had been put forward a long time ago. However, it was established that the normal nuclear density is too low, it is not sufficient to condensate $\pi$-mesons. This is why the $\

Formation of PAHs and Carbonaceous Solids in Gas-Phase Condensation Experiments [PDF]

open access: yes, 2009
Carbonaceous grains represent a major component of cosmic dust. In order to understand their formation pathways, they have been prepared in the laboratory by gas-phase condensation reactions such as laser pyrolysis and laser ablation.

Selecting and Installing Energy-Efficient Windows to Improve Dwelling Sustainability

open access: yesVitruvio: International Journal of Architectural Technology and Sustainability, 2017
Windows play a significant role in achieving comfort in buildings by letting in natural light, solar warmth, fresh air and permitting outdoor views. On the other hand, poor quality windows can be the source of overheating or unwanted infiltration or ...

One-loop Correction and the Dilaton Runaway Problem [PDF]

open access: yes, 1995
We examine the one-loop vacuum structure of an effective theory of gaugino condensation coupled to the dilaton for string models in which the gauge coupling constant does not receive string threshold corrections.
