SIMULATION OF SYSTEM FOR REPRODUCTION OF HIGH INTENSITY HEAT FLUX

Ukrainian Metrological Journal, 2020
Control of integral heat losses energy facilities during operation and fire tests are accompanied by an intensive heat transfer process in which the values of the surface heat flux reach about 200 kW/m2. Measurement of the heat flux is carried out using contact (heat flux sensors) and contactless (radiometers of measuring instruments) sensors, which ...

Estimation of the height of intense turbulent heat exchange layer in the stably stratified atmospheric boundary layer

Atmospheric and Ocean Optics, 2020
The relation of the height of intense turbulent heat exchange layer in the atmospheric boundary layer to the air temperature gradients, wind velocity, and turbulent heat flux in the atmospheric surface layer has been analyzed.

Composite Heat Shields in Intense Energy Fluxes with Diffusion

Russian Engineering Research, 2019
A method is proposed for bench testing of reusable composite samples under intense thermal and ionizing radiation. Tests are conducted under intense energy fluxes. As a result of the tests, the temperature field and the displacement field at the surface of heat-shielding composite and in its depth are determined at different times.

Study on transient heat flux intensity factor with interaction integral

International Journal of Thermal Sciences, 2019
Abstract Aim at determining of the heat flux intensity factor (HFIF) near a crack tip in structures under transient heat flux load, the transient JT integral is defined firstly and proved to be path-independent. Based on the path-independence of the transient JT integral, a transient interaction integral utilized to extract the transient HFIF is ...

The Importance of Photospheric Intense Flux Tubes for Coronal Heating

Solar Physics, 1997
Dissipation of magnetic energy in the corona requires the creation of very fine scale-lengths because of the high magnetic Reynolds number of the plasma. The formation of current sheets is a natural possible solution to this problem and it is now known that a magnetic field that is stressed by continous photospheric motions through a series of ...

A Persistent and Intense Marine Heatwave in the Northeast Pacific During 2019–2020

Geophysical Research Letters, 2021
Motivated by increasing marine heatwaves (MHWs) and their dramatic climate effects, we analyze the persistent 2019–2020 MHW, which showed significant positive sea surface temperature (SST) anomalies in the Northeast Pacific.
