The error in gas temperature measurements with thermocouples. Application on an SOFC system Heat Exchanger

We develop a mathematical model and simulate the measurement of gas temperatures as applied by insertion of a thermocouple into a gas stream in order to integrate this model in a model that simulates the Heat Exchanger of an SOFC system. The model is valid ...

Heat transfer to liquid metal: Review of data and correlations for tube bundles

Konstantin Mikityuk

Four sets of experimental data (total of 658 data points) for heat transfer to liquid metals (NaK of different compositions and Hg) flowing in a triangular or square lattice of cylindrical rods with pitch-to-diameter ratios of 1.1 up to 1.95 for a wide ran ...

Analysis of a biorefinery integration in a bisulfite pulp process

François Maréchal, Zoé Périn-Levasseur

Process integration techniques have been applied to study a bisulfite mill which produces pulp and three additional by- products: bioethanol, lignosulfonate and yeast. Particular attention was devoted to the integration of the chemical recycling loops whic ...

Boiling on a tube bundle

Francesco Agostini

The complexity of the two-phase flow in a tube bundle presents important problems in the design and understanding of the physical phenomena taking place. The working conditions of an evaporator depend largely on the dynamics of the two-phase flow that in t ...

Visualization of R-134a Flowing on Tube Arrays with Plain and Enhanced Surfaces under Adiabatic and Condensing Conditions

John Richard Thome, Daniel Gstöhl

Experimental studies were performed to investigate the flow patterns of liquid films of R-134a on vertical arrays of horizontal tubes under adiabatic test conditions at room temperature and during condensation at a saturation temperature of 304 K. Three ar ...

Comparison of the transient behaviour of LBE-and gas-cooled experimental accelerator-driven systems

Rakesh Chawla, Konstantin Mikityuk

The paper presents a comparison of transient calculations for two 80-MWt MOX-fuelled experimental accelerator-driven systems (XADS), one cooled by lead-bismuth eutectic and the other by helium. The results for protected (with accelerator beam trip) and unp ...

Advanced Power Plant Design Methodology using Process Integration and Multi-Objective Thermo-Economic Optimisation

François Maréchal, Daniel Favrat, Raffaele Bolliger

Thermo-economic modelling techniques are well known techniques to optimise power plant designs. These methods are usually based on the definition of a superstructure that includes the major options of the design. If this approach has proved to be appropria ...
