Statistical Saturation of Buoyant Flow Induced by a Fluctuating Acceleration
We study buoyancy driven convection in a laterally heated and two dimensional cavity under a uctuating acceleration eld, to model ow conditions in a microgravity environment. In the limit of a large aspect ratio cavity, (the length in the direction perpendicular to the temperature gradient is much larger than in the parallel direction), an analytic solution can be found in which the ow reaches ...
متن کاملMathematical Modeling of Micropolar Blood Flow in a Stenosed Artery Under the Body Acceleration and Magnetic Field
Blood flow is modeled as non-Newtonian micropolar fluid. The non-linear governing equations of continuum and momentum in the cylindrical coordinate are being discretized using a finite difference approach and have been solved iteratively ,through Crank-Nicolson method. The blood velocity distribution, volumetric flow rate and Resistance to blood flow at the stenosis throat are computed for vari...
متن کاملDirect Simulations of Particle Acceleration in Fluctuating Electromagnetic Field across a Shock
We simulate the acceleration processes of collisionless particles in a shock structure with magnetohydrodynamical (MHD) fluctuations. The electromagnetic field is represented as a sum of MHD shock solution (B0,E0) and torsional Alfven modes spectra (δB, δE). We represent fluctuation modes in logarithmic wavenumber space. Since the electromagnetic fields are represented analytically, our simulat...
متن کاملNumerical Investigation of Magnetic Field Effects on Mixed Convection Flow in a Nanofluid-filled Lid-driven Cavity
In this work, the stencil adaptive method is applied to investigate the effects of a magnetic field on mixed convection of Al2O3-water nanofluid in a square lid-driven cavity. The incompressible Navier-Stokes equations are solved by an adaptive mesh method which has superior numerical advantages compared to the traditional method on the uniform fine grid. The main objective of this study is to ...
متن کاملUltracold Fermions in a Cavity-Induced Artificial Magnetic Field.
We propose how a fermionic quantum gas confined to an optical lattice and coupled to an optical cavity can self-organize into a state where the spontaneously emerging cavity field amplitude induces an artificial magnetic field. The fermions form either a chiral insulator or a chiral liquid carrying chiral currents. The feedback mechanism via the dynamical cavity field enables robust and fast sw...
