Gravity-Induced Thermal Rectification in Gaseous Systems
Rongxiang Luo, Chao Yang, Juncheng Guo +1
Thermal rectification (TR) typically relies on structural asymmetry or material heterogeneity. Here, we show that gravity alone can induce and modulate TR in gaseous systems. Using…
Heat Conduction in Momentum-Conserving Fluids: From quasi-2D to 3D systems
Rongxiang Luo, Jiaqi Wen, Juncheng Guo
Using nonequilibrium and equilibrium molecular dynamics simulations, we investigate heat conduction in a momentum-conserving mesoscopic fluid modeled by multiparticle collision dyn…
Gravity-Induced Modulation of Negative Differential Thermal Resistance in Fluids
Qiyuan Zhang, Juncheng Guo, Juchang Zou +1
We investigate how gravity influences negative differential thermal resistance (NDTR) in fluids modeled by multiparticle collision dynamics. In the integrable case, we derive the h…
Multi-particle-collision simulation of heat transfer in low-dimensional fluids
Rongxiang Luo, Stefano Lepri
Simulation of transport properties of confined, low-dimensional fluids can be performed efficiently by means of Multi-Particle Collision (MPC) dynamics with suitable thermal-wall b…
Heat conduction in low-dimensional electron gases without and with a magnetic field
Rongxiang Luo, Qiyuan Zhang, Guanming Lin +1
We investigate the behavior of heat conduction in two-dimensional (2D) electron gases without and with a magnetic field. We perform simulations with the Multi-Particle-Collision ap…
