[1] We studied the thermomechanical effects on surface heat flow near major faults from positive feedback between temperature-dependent thermal conductivity k(T)∝ (1/T) and frictional heating in a crust-lithosphere system using finite element simulations. Variable conductivity and frictional heating cause a drastic reduction in the thermal conductivity, and these changes can impact the heat flu...

In this paper, the effect of cold air on the fluid flow inside the cylindrical combustion chamber and its wall temperature distribution have been studied computationally, taking into account the effect of radiative heat transfer from hot gases. The results have been compared with the case that radiative heat transfer was neglected. It is observed that the reattachment length increases when incr...

The present numerical attempt deals the sway to transfer of heat and mass characteristics on the time-dependent hydromagnetic boundary layer flow of a viscous fluid over an exponentially inclined preamble stretching. Furthermore, the role of viscous heating, thermal radiation, uneven energy gain or loss, velocity slip, thermal slip and solutal slips are depicted. The prevailing time-dependent P...

A fundamental problem in heat transfer is the convective cooling of the heated walls of a channel. We find steady two-dimensional (2D) flows that maximize the heat removed from fixed-temperature walls for a given rate of energy used to drive the flow, Pe (Pe is the Peclet number, a dimensionless flow speed). For parabolic (Poiseuille) flow, the heat transfer scales as Pe. Starting from Poiseuil...

Abstract In the present paper, a theoretical analysis is made to investigate fluid flow and heat energy transformation features of single multi-walled water functionalized carbon nanotubes (CNTs) with uniform inconstancy boundary conditions onward flat plate. The liquid motion momentum transfer have been analyzed using homogeneous model. Both single-wall CNTs (SWCNTs) multi-wall (MWCNTs) used b...

The dynamical role of geothermal heating in abyssal circulation is reconsidered using three independent arguments. First, we show that a uniform geothermal heat flux close to the observed average (86.4mWm−2) supplies as much heat to near-bottom water as a diapycnal mixing rate of ∼10−4 m2 s−1 – the canonical value thought to be responsible for the magnitude of the present-day abyssal circulatio...
