In this paper, we consider numerical approximations of a hydro-dynamically coupled phase field diblock copolymer model, in which the free energy contains a kinetic potential, a gradient entropy, a Ginzburg-Landau double well potential, and a long range nonlocal type potential. We develop a set of second order time marching schemes for this system using the “Invariant Energy Quadratization” appr...

Turbulent mixing exerts a significant influence on many physical processes in the ocean. In stably stratified Boussinesq fluid, this irreversible describes conversion of available potential energy (APE) to background (BPE). some settings APE framework is difficult apply and approximate measures are used estimate mixing. For example, numerical simulations turbulence often use triply periodic dom...

Microwave (MW) offers a unique heating mechanism, which volumetrically pushes internal moisture to the surface during drying of water-rich foods such as fish. However, due uneven power distribution, continuous application MW energy causes excessive localized heating, resulting in deterioration food quality. Incorporation other techniques convective, vacuum, osmotic, and freeze-drying with has b...

In this paper we present a unified shell model for stably stratified and convective turbulence. Numerical simulation of this model for stably stratified flow shows Bolgiano-Obukhbov scaling in which the kinetic energy spectrum varies as k(-11/5). The shell model of convective turbulence yields Kolmogorov's spectrum. These results are consistent with the energy flux and energy feed due to buoyan...

An empirical potential energy surface has been developed for the Ne·OH/D complexes from the experimentally observed vibrational and rotational energy levels with ab initio calculations being used for initial esti-

We derive a new formalism for convective motions involving two radial flows. This formalism provides a framework for convective models that guarantees consistency for the chemistry and the energy budget in the flows, allows time-dependence and accounts for the interaction of the convective motions with the global contraction or expansion of the star. In the one-stream limit the formalism reprod...

Currently available evidence for the mechanisms thought to be responsible for large-scale charge separation in thunderclouds is reviewed. The evidence suggests that electrically charged precipitation particles are basic to the electrification process but that convective motions are essential in accounting for the electrical energy of active thunderstorms. The relative contributions of air and p...
