Responsible for the development and experimental evaluation of SIMAS: Abengoa's C++ performance models of parabolic through power plants. These models are currently used to compare the efficiency of different technologies and available commercial products as well as in the engineering design of commercial plants in Abengoa. Te models were thoroughly tested in our facilities under different fluids: thermal oil, water (direct steam generation), and molten salts.
- 1D piping flow model, heat losses, pressure drop, solar optical efficiency.
- Solar Field model. Thermal storage model. Power block model.
- Yearly simulation with meteorologic data.
Manager of the molten salts receiver tube project where we successfully designed high temperature receiver tube for nitrate molten salts. Worked in junction with our american team in Denver for the design of the flexible hose joints between collectors.
- Personally designed the receiver tube: materials selection, fluid mechanics, thermal and stress mechanics.
Developer team member of the Solar Collector Optical Simulation Program: a ray tracing Monte Carlo simulation program in C++ for the optical characterization of concentrating solar systems.
- Deformation of the support structure of the mirrors.
- Stochastic mounting misalignment of optic modules.
- Surfaces optical characterization.
Creator and developer of the refined emittance measurement method: as part of the team that developed solar characterization and measurement equipment I developed the novel procedure to calculate the emittance of the receiver tube from thermal losses with a 5% increased accuracy.
- Article under review for publication on Elsevier's Solar Energy journal.
- Based on a non-gray surface radiation model (spectral dependent reflectance of the absorber tube).
Currently responsible for the thermo-mechanical design of a high temperature corrosion test vessel: where the chemical stability and corrosion kinetics of different materials exposed to 700-1000 ºC molten salts will be tested under rotative motion conditions to simulate the effect of flow velocity on corrosion.
Developer of solar disk test bench: an ingenious two cooling system scheme to transform a Sterling solar disk into a solar coating thermal shock resilience testing bench.
- Using an air and water cooling system to achieve a high and low temperature stability (700ºC-200ºC)
- Managing a cooling trend control from 5ºC/min to 1º/min
Discoverer of the reason for the unexpected increase frequency of cracking receiver tubes during operation of through plants after a new control system was released. It was caused by a previously undetected stress on the glass envelope that took place during partial defocus of the collectors.
- Crack mechanics and thermal fatigue on glass receiver tube.
