The heat conductivity mechanism of the IR heating propagation for surfaces decontamination in protected ground [PDF]
E3S Web of Conferences, 2023 Modern greenhouses usually have flat concrete surfaces with communications for subsurface and above surface heating. It is proposed to disinfect surfaces with infrared radiation. We solve the corresponding heat equation.

THE CONTACT-SURFACE HEAT UTILIZER [PDF]
Theory and Building Practice, 2020 У промисловості застосовуються контактно-поверхневі теплообмінники. В цих апаратах реалізується глибоке охолодження продуктів спалювання (30–40 оC). При розрахунку контактно-поверхневих теплообмінників поверхневий коефіцієнт передачі повного тепла для насадкової камери є найважливішим фактором, що визначає як контактну частину, так і зведений ...
