The balance laws, which govern the response of a finite domain, can be converted to field equations that are valid at each point of the body. Let us first focus on Equation (4.157) that expresses the time rate of change of mass in the reference configuration. In this equation, the ...
This work aims to simulate the impacts of exothermic reaction and Soret–Dufour numbers on the double diffusion of Nano Enhanced Phase Change Materials (NEPCM) inside a porous annulus. The complex rectangular annulus contains two ellipses and two triangl
443 factors on glacier mass balance. These relationships are considered not only from a whole HMA perspective but also by investigating individual mountain region. Overall, the driving mechanism of the spatial heterogeneity of glacier mass balance in the HMA is examined from a new perspective. 2 ...
41 adopted the volume-of-fluid method to examine NEPCM inside a spherical container. Nabeal et al.42 conducted experimental and numerical studies on the melting procedure of NEPCM in a circular cylinder with heat flux. Their results introduced the efficiency of nanoparticles in enhancing the ...
In the following, we want to investigate the NC effects (appearing in the Fermi EoS) in a semi-classical regime describing a spherical symmetric ball made of Fermi gas. Hence we consider the usual Poisson equation for the gravi- tational potential φ ∇2φ = 4π Gρ (10) where G is...
or tied to an atom’s nucleus. the energy levels of electrons in atoms are represented by spherical shells of varying radii. the unit electrical charge is defined as the charge on a single electron. q4 where do protons get their mass? these particles are made up of three quarks that are...
Since a rocket-propelled spacecraft in free flight derives its only acceleration from discharge of propellant mass, its equation of motion follows directly from conservation of the total momentum of the spacecraft and its exhaust stream: (1)mυ.=m.υe, where m is the mass of the spacecraft...
A balance of particles over a cylindrical volume permits to calculate further estimates of the particle radial flux, used for testing of the results. The detailed study of the spatial distribution of particles has been made up to 10 nozzle diameters (10D) from the jet exit, in five ...
Coronal mass ejections (CMEs) are the largest-scale eruptive phenomenon in the solar system, expanding from active region-sized nonpotential magnetic structure to a much larger size. The bulk of plasma with a mass of ∼ 1011,1013 kg is hauled up all the way out to the interplanetary spac...
