Uniform temperature profile for a dense array CPV receiver under non uniform illumination profile

AIP conference proceedings (2014)

Sara Riera Jérôme Barrau Arnaud Perona Alain Dollet Joan Rosell

Previous experimental and numerical studies of hybrid cooling devices for CPV receivers were developed under uniform illumination profile conditions; but literature review shows that this uniformity assumption is difficult to satisfy in real conditions. This investigation presents the design and the validation of a hybrid cooling device able to tailor its local heat extraction capacity to 2D illumination profiles in order to provide a uniform temperature profile of the PV receiver as well as a low global thermal resistance coefficient. The inputs of the design procedure are the solar concentration, the coolant flow rate and its inlet temperature. As the illumination profile is 2D dependent, a matrix of pin fins is implemented and a hybrid Jet Impingement /Matrix of Pin Fins cooling device is experimentally tested and compared to a hybrid Jet Impingement / Microchannels cooling device developed previously. The results demonstrate similar performances for both designs. Furthermore, in contrast to the cooling scheme using longitudinal fins, the distribution of the pin fins can be tailored, in two dimensions, to the local need of heat extraction capacity.

MAIN FEATURES OF MEGATURBIDITES IN THE EOCENE OF SOUTHERN PYRENEES

Annales Societatis Geologorum Poloniae/Rocznik Polskiego Towarzystwa Geologicznego (1989)

Joan Rosell Józef Wieczorek

Glowne cechy megaturbiditow z eocenu poludniowych Pirenejow Eocene sequences of the Ager-Jaca-Pamplona Basin and Terrades-Ripoll-Cadi Basin Basin in the southern Pyrenees include carbonate megaturbidites. The main features of the megaturbitides are: (i) unusually great thickness. (ii) petrographical composition different from that of their host sequences, (iii) the presence of lower chaotic segment (breccia), and upper organized segment (grading), (iv) large lateral extent, (v) lateral variability of internal organization of beds, (vi) independence of the fan systems, (vii) transport directions different than in normal turbidites. These features are also characteristic of many other carbonate megaturbidites described from various sequences of Alpine Europe. Siliciclastic megaturbidites are less common: they are featured by their smaller thickness and the lack of the lower, chaotic part.

Chronology and paleoenvironmental interpretation of talus flatiron sequences in a sub‐humid mountainous area: Tremp Depression, Spanish Pyrenees

Earth Surface Processes and Landforms (2013)

Carles Roqué i Pau Rogelio Linares Mario Zarroca Joan Rosell Xavier M. Pellicer

ABSTRACT Talus flatirons are debris‐covered relict slopes, disconnected from the source area, which are relatively common in arid and semi‐arid areas. Talus flatiron sequences record the alternation of accumulation and incision phases. These chronosequences may be used for infer temporal changes in the morphogenetic processes acting on the slopes as well as information on the local paleoclimatic history. Talus flatiron sequences developed in the Tremp Depression, eastern Spanish Pyrenees, are analysed from the geomorphological, chronological and paleoenvironmental perspective. The two groups of relict slopes differentiated by means of detailed geomorphological mapping have been dated by optically stimulated luminescence (OSL) and radiocarbon dating at 25–20 kyr (S3) and 5·4–1·7 cal kyr (S2). The talus flatiron group S3 is correlated with a fluvial terrace of the Noguera Pallaresa River ( c . 23 kyr bp ). The comparison of the ages obtained in the Tremp Depression with chronologies published for talus flatiron sequences in semi‐arid areas and other paleoclimatic proxies suggests that the aggradation phases in the slopes occurred during periods with higher humidity and vegetation cover. The chronological differences observed between semi‐arid Spain and the Tremp Depression may be partly related to the more humid climate of the latter mountain area.
