suppression of coke formation in thermal cracking by coke inhibitors
the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...
15 صفحه اولEnhanced vertical inhomogeneity in turbulent rotating convection.
In this Letter we report experimental evidence that rotation enhances vertical inhomogeneity in turbulent convection, in spite of the increased columnar flow ordering under rotation. Measurements using stereoscopic particle image velocimetry have been carried out on turbulent rotating convection in water. At constant Rayleigh number Ra=1.11 x 10(9) several rotation rates have been used, so that...
متن کاملThermal convection in a rotating layer of a magnetic fluid
Thermal convection in magnetic fluids can be driven by buoyancy or by magnetic forces (due to the thermomagnetic effect). Depending on the direction of the applied temperature gradient, buoyancy effects can be stabilizing (heating from above) or destabilizing (heating from below), whereas the magnetic forces always play a destabilizing role for magnetic fields perpendicular to the interface. We...
متن کاملSpatial structure of the thermal boundary layer in turbulent convection
We have measured the mean temperature profiles T̄(z) and the thermal layer thickness d th(x ,y) at various horizontal positions on the lower plate of a cylindrical convection cell, using water as the working fluid. The Rayleigh number Ra in the experiment varied from 2310 to 2310. The normalized vertical temperature profiles measured at various positions x along the direction of large scale circ...
متن کاملThermal convection in a nonlinear non-Newtonian magnetic fluid
We report theoretical and numerical results on thermal convection of a magnetic fluid in a viscoelastic carrier liquid. The viscoelastic properties are described by a general nonlinear viscoelastic model that contains as special cases the standard phenomenological constitutive equations for the stress tensor. In order to explore numerically the system we perform a truncated Galerkin expansion o...
