Heating rate effects in the transient nucleation problem.
نویسنده
چکیده
The matched asymptotic (singular perturbation) treatment of the nucleation equation [V. A. Shneidman, Sov. Phys. Tech. Phys. 32, 76 (1987); 33, 1338 (1988)] is modified to include finite heating rate effects, which follow the isothermal transient stage. Despite the complicated mathematical structure of the discrete Becker-Doring equation, the obtained analytical solution is shown to be accurate numerically. The described situation is typical for two-step annealing crystallization studies and can lead to reinterpretation of some of the classical experiments.

Thermal recovery involves well-known processes such as steam injection (cyclic steam stimulation, steam drive, and steam-assisted gravity drainage), in situ combustion, and a more recent technique that consists of heating the reservoir with electrical energy. When high frequency is used for heating, it is called electromagnetic (EM) heating. The applications of EM heating for heavy-oil reservoi...
متن کاملIn Situ Measurements Reveal Phase and Texture Evolution in Solution Deposited Pzt Thin Films
Heating rate during crystallization is known to affect the final texture obtained in lead zirconate titanate thin films. The transient/intermediate phases present in the thin film during perovskite phase nucleation have been suggested to cause this variation in texture with heating rate. To understand the interrelationship between the transient/intermediate phases and the texture in the final p...
متن کاملDoes Shear Heating of Pore Fluid Contribute to Earthquake Nucleation?
[1] Earthquake nucleation requires reduction of frictional strength = ( p) with slip or slip rate, where , n, and p are the friction coefficient, normal stress, and fluid pressure, respectively. For rate state at fixed ( p), instabilities can occur when d ss/dv < 0, where ss is the steady state friction and v is slip rate. Shear heating increases p and, if dilatancy and pore pressure diffusion ...

An analytical investigation is conducted to study the unsteady free convection heat and mass transfer flow through a non-homogeneous porous medium with variable permeability bounded by an infinite porous vertical plate in slip flow regime while taking into account the thermal radiation, chemical reaction, the Soret number, and temperature gradient dependent heat source. The flow is considered u...
