Starting from the prototype constructed the previous year and the preliminary results gathered, numerical simulations have been conducted to investigate the research hypothesis of weaker Marangoni convection at higher absorption temperatures and the existence of a possible temperature limitation where the phenomenon is not observable. Additionally, the design and assembling of an advanced test section where an extended temperature range can be tested and real time absorption rate can be measured from high precision initial temperature and concentration conditions while performing direct visual observations of the interfacial turbulence as well as the internal velocity field using UV-light-irradiated fluorescent uranine and Particle Image Velocimetry measurements, respectively. The numerical model is referred for dynamic simulation published in the journal Applied thermal Engineering [1] and numerical results are summarized in a conference paper [2] to be presented in August 2023 at the 26TH INTERNATIONAL CONGRESS OF REFRIGERATION, in Paris (France). These results confirm the research hypothesis and were used for guiding the design of the testing equipment that is presently being assembled by showing that, contrarily to common absorption, higher solution temperatures yield a reduction of the absorption rate of approximately 33% as the temperature increases from 30°C to 80°C. Following experimental measurements of the absorbed mass and numerical simulations will be performed to support, argue and quantify the suggested conclusions. Finally, the physical understanding gained in this study will be used to guide the design and control of absorption heat pumps (heat amplifiers and heat transformers).
