Heat loss evaluation of an experimental set-up for predicting the initial stage of the boiling curve for water at low pressure.
Proceedings 7th Annual Comsol Conference.
Konferenzveröffentlichung, Bibliographie
Kurzbeschreibung (Abstract)
In this paper heat losses and gains are assessed for a specific measuring set-up improving the validity of performance data to accurately predict the initial stage of a boiling curve. Simulation focus on achieving results predicting real measuring data of a plain surface structure. Therefore, the relevant components of the measuring set-up have been implemented in a 2-D axisymmetric model combining the Physics `Heat Transfer in Fluids - laminar flow' with `Heat Transfer in Solids'. The operability of the model has been proven analyzing the simulation results and the influence of heat losses and gains are investigated by varying model parameters. Finally, the measured and simulated results of the plain surface structure are compared to literature.
