Non-contact heat flux measurement using a transparent sensor [PDF]

A working non-contact heat flux sensor was demonstrated using a transparent material (sapphire) and a multiwavelength pyrometer. The pyrometer is used to measure the temperatures of the two surfaces of the sensor from the spectrum of radiation ...

Control of heat flux using computationally designed metamaterials [PDF]

, 2016
To gain control over the diffusive heat flux in a given domain, one has to design metamaterials with a specifc distribution of the generally anisotropic thermal conductivity throughout the domain.

Modulation of near-field heat transfer between two gratings

, 2011
We present a theoretical study of near-field heat transfer between two uniaxial anisotropic planar structures. We investigate how the distance and relative orientation (with respect to their optical axes) between the objects affect the heat flux.

Advanced high temperature heat flux sensors [PDF]

To fully characterize advanced high temperature heat flux sensors, calibration and testing is required at full engine temperature. This required the development of unique high temperature heat flux test facilities. These facilities were developed, are in

Magneto-thermoplasmonics: from theory to applications

, 2018
We review recent theoretical developments on the nanoscale radiative heat transfer in magneto-optical many-particle systems. We discuss in detail the circular heat flux, the giant magneto-resistance effect, the persistent heat current, and the thermal ...

Modeling of heat flux on the main limiter in EAST

Nuclear Fusion
Heat flux on plasma-facing components is one of the key issues in tokamak operation. In EAST, severe damages occurred on the main limiters due to high heat loads limit high-power and long-pulse operation in recent campaigns.

Conductivity Identification in the Heat Equation by the Heat Flux

Journal of Mathematical Analysis and Applications, 1999
The author considers the problem of determining the thermal conductivity of a semi-infinite rod, given the temperature and heat flow at the endpoint. That is, given \(f\) on \([0,T[\) and \(g\) on \(]0,T[\), determine a positive continuous function \(\varphi\) on \([0,T[\) such that the problem \[ \begin{aligned} u_t(x,t)= \varphi(t)u_{xx} (x,t)\quad &\

Heat flux calibration facility capable of SSME conditions [PDF]

There is a need to more thoroughly characterize the hostile space shuttle main engine (SSME) turbopump environment. It has been estimated that component surface heat flux in the hot-gas environment is about 10 MW/square meter, and this is about 50 times ...
