[1] Topographic profiles across a lobate fault scarp on Mercury have been used to constrain the depth of faulting to 30–40 km. Here we use this depth to place constraints on the crustal thickness and heat flow into the base of the crust. With no crustal heat production, the mantle heat flux on Mercury at the time of scarp formation was 30–50 mWm . However, higher crustal heat production rates a...

Atmospheric surface layer (ASL) experiments over the past 10 years demonstrate that the flux-variance similarity functions for water vapour are consistently larger in magnitude than their temperature counterpart. In addition, latent heat flux calculations using the flux-variance method do not compare as favorably to eddy-correlation measurements when compared to their sensible heat counterpart....

A heat transfer model has been developed that uses quasi-steady heat flux relations to calculate the heat transfer from combustion gases through the cylinder wall to the coolant in an internal combustion engine. The treatment of convective heat transfer accounts for the physical problems of rotating and impinging axial flow inside the engine cylinder. The radiative heat transfer includes gas ra...

To gain control over the diffusive heat flux in a given domain, one needs to engineer a thermal metamaterial with a specific distribution of the generally anisotropic thermal conductivity throughout the domain. Until now, the appropriate conductivity distribution was usually determined using transformation thermodynamics. By this way, only a few particular cases of heat flux control in simple d...

In order to understand a heat transfer phenomenon, it is sometimes very important to know the change in heat flux and temperature with time or the distribution of the heat flux and temperature on the surface of a heating block. Furthermore, with the development of computational thermal-fluid dynamics, experimental data that are of the CFD level, both spatially and temporally, are needed to vali...

Heat-transfer through weakly magnetized diffuse astrophysical plasmas excites whistlers. This leads to electron whistler resonant scattering, a reduction of the electron mean-free path, and heat-flux inhibition. However, only whistlers propagating at a finite angle to the magnetic field (off-axis) can scatter the heat-flux carrying electrons. Thus, the level of heat flux-inhibition along the ma...

High heat flux component manufacture is the critical technology for the current fusion experimental devices and fusion reactors in the future since it will face fusion plasma directly and endure high flux particle irradiation and huge heat deposition from core plasma. Be/CuCuZr/ss, W/CuCrZr and CFC/CuCrZr modules have been selected as the high heat flux components for ITER first wall and divert...

We present a revised estimate of Earth’s surface heat flux that is based upon a heat flow data-set with 38 347 measurements, which is 55% more than used in previous estimates. Our methodology, like others, accounts for hydrothermal circulation in young oceanic crust by utilising a half-space cooling approximation. For the rest of Earth’s surface, we estimate the average heat flow for different ...

The unsteady stagnation point flow and heat transfer with prescribed flux towards a stretching and shrinking sheet with viscous dissipation is studied. Similarity transformation is adopted to initially convert the governing differential equations into nonlinear ordinary differential equations. The two-point boundary value ordinary differential equations (ODE) are subsequently converted into par...

Infrared thermography is used in TCV to measure the heat flux deposited onto the graphite tiles of the inner wall. The heat flux radial profile is found to be well described by the sum of a main parallel component and a non negligible cross-field component. The latter accounts for about 20% of the deposited heat flux. The parallel component shows an enhancement around the contact point in all d...
