Thermal and Dynamic Study of Convection-Radiation Coupling in a Closed Enclosure
Sanembaye Adrien, Konfé Amadou, Toussakoe Karim, KY Thierry Sikoudouin Maurice and Bathiebo Dieudonné JosephIn this work, we present a two-dimensional study of natural convection in a square air-filled cavity whose two vertical sides are subjected to a temperature difference, while the other two horizontal ones are adiabatic. The numerical method used is that of finite elements used in the COMSOL...

Updated Observing Scenarios and Multimessenger Implications for the International Gravitational-wave Networks O4 and O5
R. Weizmann Kiendrebeogo, Amanda M. Farah, Emily M. Foley, Abigail Gray , Nina Kunert, Anna Puecher, Andrew Toivonen, R. Oliver VandenBerg, Shreya Anand, Tomás Ahumada, Viraj Karambelkar, Michael W. Coughlin , Tim Dietrich, S. Zacharie Kam , Peter T. H. Pang , Leo P. Singer , and Niharika SravanAn advanced LIGO and Virgo’s third observing run brought another binary neutron star merger (BNS) and the first
neutron-star black hole mergers. While no confirmed kilonovae were identified in conjunction with any of these
events, continued improvements of analyses surrounding GW170817 allow...

Establishment of a model for the calculation of the COP of a solar adsorption refrigerator
KONFE Amadou, NANA G Gilbert, OUEDRAOGO Salif, KAM SiéThis paper deals with the evaluation of the Coefficient of Performance (COP)
of solar adsorption refrigeration. In the literature, simulation models to predict
the thermal behaviour and the coefficient of performance of these systems
are uncommon. This is why we suggest a model to simulate...
