Cost reduction of solar thermal plants by advanced thermalhydraulic design methods
(Journal of Physics: Conference Series, 2019-09-04)
CoolShift – Cooling of buildings by chiller-assisted nocturnal radiation and convection
(IOP Publishing, 2019-09-04)
A novel approach for cooling an office building is numerically evaluated. PVT collectors are used for nocturnal radiative and convective cooling. A TABS ceiling serves as thermal storage. If the free cooling power of the ...
Pipe Network Analysis for Solar Thermal Plants
(ISES Conference Proceedings, 2018-09-10)
Efficiency, cost-effectiveness and operational safety of solar plants must be based on the knowledge of pressure loss as well as flow distribution and temperature distribution of branched collector arrays. Therefore, pipe ...
An Explicit and Continuous Friction Factor Correlation for Helical Tubes with Arbitrary Roughness
Convergence of numerical schemes for pipe network analysis requires continuous modelling of pressure losses in the transition region between laminar and turbulent regions. Several existing correlations for the friction ...
A thermal-hydraulic model for the stagnation of solar thermal systems with flat-plate collector arrays
Stagnation is the transient state of a solar thermal system under high solar irradiation where the useful solar gain is zero. Both flat-plate collectors with selective absorber coatings and vacuum-tube collectors exhibit ...
