The capacitance of approximately conical scanning capacitance microscope probes placed perpendicularly over a conducting plane has been modelled using the finite element method. The dependence on tip/surface distance, radius of curvature of the tip apex, cone angle and height has been analysed. Both shielded and unshielded probes have been considered. The(More)
Computational Fluid Dynamics (CFD) simulations of internal loop reactor for heavy oil slurry bed hydroprocessing have been done in commercial code Fluent 6.3 using Euler two-phase flow model and standard k-ε turbulence model. The effects of the physical properties on the flow field in the reactor are investigated. The results show that the gas density has(More)
