    Temperature effects on the dynamics of oppositely charged bipolarons scattering in conjugated polymers

    Within a tight-binding electron–phonon interaction model modified to include temperature effects, the dynamics of two oppositely charged bipolarons scattering in conjugated polymers are investigated using a no...

    Effects of Geometry Parameters on the Cooling Performance and Conjugate Thermal-Elastic Property of Double-Reverse-Jet Film Cooling

    In order to investigate the double-reverse-jet film cooling (DRJFC), the multi-field coupling calculating method is used to study the effect of geometric parameters on the resultant vortex structure and conjug...

    α1, β1, β2 - root characteristics of multiply possible theoretical solutions of steady Mach reflections in perfect diatomic gases

    The existence of the jump in β1=β2 double roots in the three-shock theoretical solutions of steady Mach reflections on the (θ1, M0) plane is determined for the first time, θ1 is flow deflection behind the inciden...

    Variational calculations of ionized-donor-bound excitons in GaAs-Al x Ga 1 - x As quantum wells

    Using a two-parameter wave function, we calculate variationally the binding energy of an exciton bound to an ionized donor impurity (D+,X) in GaAs-AlxGa1-xAs quantum wells for the values of the well width from 10...

    A Navier-Stokes Solver Using Edge-Based Smoothing

    A three dimensional Navier-Stokes solver based upon the one—step Lax—WendrofF scheme has been developed. The numerical smoothing term added to the basic scheme is derived by using the TVD approach and implemen...

    A computational technique for high enthalpy shock tube and shock tunnel flow simulation

    A contact discontinuity tracking method with a specially designed moving grid is developed to eliminate the interface smearing completely. In order to precisely locate the contact surface, an updated Riemann ...

    Shock waves and turbulence in a hypersonic inlet

    A numerical investigation for an axisymmetric hypersonic turbulent inlet flow field of a perfect gas is presented for a three-shock configuration consisting of a biconic and a cowl. An upwind parabolized Navie...

    Sound Wave Structures Downstream of Incident Propagating Oblique Shock Waves

    Graphical illustration for the sound wave structure downstream of a moving incident oblique shock is presented for weak and strong Mach reflections (MR). For experimentally observed MR-like phenomena, where th...
