Assessing the Performance of Hypersonic Inlets by Applying a Heat Source with the Throttling Effect

open access: yesAerospace, 2022
Utilization of a heat source to regulate the shock wave–boundary layer interaction (SWBLI) of hypersonic inlets during throttling was computationally investigated. A plug was installed at the intake isolator’s exit, which caused throttling.

Mathematical analysis of casson fluid flow with energy and mass transfer under the influence of activation energy from a non-coaxially spinning disc

open access: yesFrontiers in Energy Research, 2022
A Casson fluid is the most suitable rheological model for blood and other non-Newtonian fluids. Casson fluids hold yield-stress and have great significance in biomechanics and polymer industries.

Analytical tuning of regulators in a cascade automatic discharge control system

open access: yesСовременная наука и инновации, 2023
When synthesizing automatic control systems, there is a problem with complex definition of controller parameters, and the main criterion becomes the achievement of stable operation, and the quality of the transient becomes of secondary importance.

Optimization Method for the Evaluation of Convective Heat and Mass Transfer Effective Coefficients and Energy Sources in Drying Processes

open access: yesEnergies, 2020
A new optimization method for the assessment of the coefficients existing in a model of drying kinetics is developed and presented in this article. This method consists of matching the drying kinetics resulting from the mathematical model with the drying

The Source of the Solar Heat [PDF]

open access: yesNature, 1872
IT gave me great pleasure to find that Captain Ericsson has taken the same views as myself with regard to the Source of the Solar Energy; but there is a certain part of his article in NATURE, vol. vi. p. 539, which I do not quite understand.
