The influence of inclination angle on void fraction and heat transfer during condensation inside a smooth tube Ghent University
Resolving impact volatilization and condensation from target rock mixing and hydrothermal overprinting within the Chicxulub impact structure Ghent University Vrije Universiteit Brussel
Fast pyrolysis with fractional condensation of lignin-rich digested stillage from second-generation bioethanol production Ghent University
Poplar-derived lignin-rich feedstock (i.e. stillage) obtained from bioethanol production was subjected to fast pyrolysis in a modified fluidised bed reactor at 430 degrees C, 480 degrees C, and 530 degrees C. The stillage was pretreated by enzymatic digestion prior to fast pyrolysis. Pyrolysis vapors were collected by fractional condensation to separate the heavy organic and aqueous phase liquids. The intention of this study was to assess the ...
Thermal energy processes in direct steam generation solar systems : boiling, condensation and energy storage Ghent University
Direct steam generation coupled is a promising solar-energy technology, which can reduce the growing dependency on fossil fuels. It has the potential to impact the power-generation sector as well as industrial sectors where significant quantities of process steam are required. Compared to conventional concentrated solar power systems, which use synthetic oils or molten salts as the heat transfer fluid, direct steam generation offers an ...
Cosmological Signature of Tachyon Condensation Vrije Universiteit Brussel
We consider the dynamics of the open string tachyon condensation in a framework of the cubic fermionic String Field Theory including a non-minimal coupling with closed string massless modes, the graviton and the dilaton. Coupling of the open string tachyon and the dilaton is motivated by the open String Field Theory in a linear dilaton background and the flat space-time. We note that the dilaton gravity provides several restrictions on the ...
Laboratory tests of window-wall interface details to evaluate the risk of condensation on windows Ghent University
Measured void fraction and heat transfer coefficients during condensation Ghent University
Most work in literature on condensation in tubes has been done for smooth tubes in the horizontal and vertical configurations. Recent experimental works with condensation at different inclination angles showed that the heat transfer characteristics were a function of inclination angle. These works were limited to heat transfer and pressure drop measurements with visual observations. However, no work has been done on measuring the void fractions ...
