Nonlinear Heat Radiation Induces Thermal Rectifier in Asymmetric Holey Composites
Asymmetric design and nonlinearity are essential to give rise to thermal rectification. In addition to the linear Fourier’s law of thermal conduction, we introduce the nonlinear thermal radiation following Stefan–Boltzmann law to asymmetric holey composites to realize the thermal rectifier. The thermal rectification results from the competition between the linear thermal conduction and the nonl...
متن کاملThermal balance and quantum heat transport in nanostructures thermalized by local Langevin heat baths.
Modeling of thermal transport in practical nanostructures requires making tradeoffs between the size of the system and the completeness of the model. We study quantum heat transfer in a self-consistent thermal bath setup consisting of two lead regions connected by a center region. Atoms both in the leads and in the center region are coupled to quantum Langevin heat baths that mimic the damping ...
متن کاملExperimental Investigation of Thermal Balance and Valve Cover Heat Transfer in a Small Internal Combustion Engine
Heat transfer in internal combustion engines is one of the most significant topics. Heat transfer may take place through thermal conduction and thermal convection in spark ignition engines. In this study, valve cover heat transfer and thermal balance of an air-cooled engine are investigated experimentally. The thermal balance analysis is a useful method to determine energy distribution and effi...
متن کاملthermal radiation heat transfer effects on single fuel droplet heat up considering it’s internal circulation
high temperatures are often encountered in almost all of the combustion systems, therefore, thermal radiation heat transfer can influence the droplets heat up rate and consequently their life time. in this paper, the effect of thermal radiation heat transfer is investigated for two cases of directional and spherically symmetric illuminations. the flow and temperature fields insdie and outside o...
متن کاملThermal Radiation, Buoyancy and Heat Generation Effects on Flow and Heat Transfer in Porous Medium
An analysis is carried out to study free convective flow and heat transfer of an viscous incompressible electrically conducting fluid over a stretching sheet. Using the similarity variable, the partial differential equations are reduced to ordinary differential equations by using R-K Gill method along with shooting technique. Numerical results of the local of the local skin friction coefficient...
