INTENSIFICATION OF HEAT TRANSFER IN HEAT EXCHANGE EQUIPMENT DURING CONDENSATION OF WATER VAPOR AFTER STEAM TURBINE INSTALLATIONS IN NUCLEAR POWER.

Energy Technologies & Resource Saving, 2023
The determining parameter that characterizes the intensity of heat transfer in heat exchange equipment is the heat transfer coefficient, the value of which depends on the thermal resistances occurring in the corresponding equipment. Thus, in the heat exchanger-condenser of a steam turbine installation of a nuclear power station, this is the thermal ...

Production of middle distillates through olefin oligomerization using ZSM‐5 as a catalyst

The Canadian Journal of Chemical Engineering, Volume 104, Issue 6, Page 3215-3227, June 2026.
Abstract The global transportation sector relies heavily on gasoline (C5–C12) and diesel (C11–C24), which together account for approximately 60% of its energy needs. Driven by rapid industrialization and urbanization, diesel consumption is outpacing gasoline, with projections estimating global demand by 2035 at 27 million barrels per day for gasoline ...

Effect of Sintering Aid Composition and Porosity on the Oxyacetylene Torch Response of Silicon Nitride for RF Windows

Journal of the American Ceramic Society, Volume 109, Issue 6, June 2026.
Silicon nitride samples were slip cast using yttrium oxide–aluminum oxide and ytterbium oxide sintering aids to fabricate plates with up to 40% porosity and compare them to a fully dense commercial standard. Silicon nitride plates were tested with an oxyacetylene torch to investigate changes in front and back face temperature, spectral emissivity ...
