Analysis of Heat Transfer Performance in a Brayton Cycle Recuperator

open access: yesBrazilian Journal of Radiation Sciences, 2021
Thermodynamic cycles are currently the most wanted means of converting nuclear power into available work due to the higher conversion efficiencies provided. Rankine cycles have been greatly applied for terrestrial reactors and nuclear submarines, while a

Using the Mid‐Holocene “Greening” of the Sahara to Narrow Acceptable Ranges on Climate Model Parameters

open access: yesGeophysical Research Letters, 2021
During the early to mid‐Holocene vegetation expanded to cover much of the present‐day Sahara. Although driven by a well‐understood difference in the orbital configuration, general circulation models have generally failed to simulate the required rainfall

DRYING OF PEARS IN CO2 MODIFIED ATMOSPHERE

open access: yesJournal of Engineering Science (Chişinău), 2023
One of the biggest problem encountered in drying area of food processing are the losses in food quality. While drying process is held, there is an important damage done to vitamins, polyphenols and other important nutriments. Being

The impact of soil moisture variability on seasonal convective precipitation simulations. Part II: sensitivity to land-surface models and prescribed soil type distributions

open access: yesMeteorologische Zeitschrift, 2013
A set of model simulations with the regional climate model COSMO-CLM (CCLM) are analysed to investigate the impact of multi-layer soil-vegetation-atmosphere transfer models (SVATs) and the prescribed soil type distribution on seasonal climate simulations.
