A Thermal-Hydraulic Model for the Stagnation of Solar Thermal Systems with Flat-Plate Collector Arrays

open access: yesEnergies, 2021
Stagnation is the transient state of a solar thermal system under high solar irradiation where the useful solar gain is zero. Both flat-plate collectors with selective absorber coatings and vacuum-tube collectors exhibit stagnation temperatures far above

Influence of suction and heat source on MHD stagnation point flow of ternary hybrid nanofluid over convectively heated stretching/shrinking cylinder

open access: yesAdvances in Mechanical Engineering, 2022
Heat flow may be improved using a new form of nanofluid known as ternary hybrid nanofluid. Magnetic field, mass suction, and heat source effects on the stagnation area of ( Cu − F e 3 O 4 − Si O 2 / polymer ) ternary hybrid nanofluid toward convectively ...

Experimental Study on Critical Flow of Supercritical CO2 at Steady State and Model Verification

open access: yesYuanzineng kexue jishu, 2022
When the loss of coolant accident happens in a reactor, because of the high temperature and high pressure in the reactor and the low external pressure, the critical flow may occur at the break due to sharp depressurization and vaporization.

Thermally stratified flow of second grade fluid with non-Fourier heat flux and temperature dependent thermal conductivity

open access: yesResults in Physics, 2018
This attempt explores stagnation point flow of second grade material towards an impermeable stretched cylinder. Non-Fourier heat flux and thermal stratification are considered. Thermal conductivity dependents upon temperature.
