    Abstract: We model the influence of Raleigh numbers in a trapezoidal cavity. One wall among the sloping walls is exposed to a heat flux density Q=100 W/ m2 and the other inclined wall is kept adiabatic. The temperature of the two horizontal walls is assumed to be constant such that Tsup=305K is greater than Tinf=300K. The equations of heat and mass transfer ... Show More

    Abstract: In this investigation, the fully differential cross sections (FDCS) for ionization of electron impact at low energy (E0 = 67 eV) were measured for the specific orientations of the molecules and around it axis. In the full perpendicular plane (FPP), the FDCS for CF4 were experimentally figured out by using reaction microscope (REMI) for different ki... Show More
