Thermal performance evaluation of pure PDMS and PDMS composites heat exchangers
Souza, Reinaldo; Nobrega, Glauco; Afonso, Inês Santos; Pereira, José; Cardoso, Elaine; Marques, Filipe; Vilarinho, Cândida; Moita, Ana; Lima, Rui A.This study investigates the heat transfer performance of three types of heat exchangers: one made of pure polydimethylsiloxane (PDMS), another incorporating recycled graphite (PDMS + Graphite 30 mass%), and a third using commercial aluminium nanoparticles (PDMS + Aluminium 30 mass%). Thermal performance was evaluated by measuring the thermal conductivity of the materials, analysing experimental convection tests...
Experimental evaluation of green nanofluids in heat exchanger made oF PDMS
Nobrega, Glauco; Souza, Reinaldo Rodrigues de; Cardoso, Beatriz D.; Afonso, Inês Santos; Pereira, José Eduardo; Cardoso, Elaine; Moita, Ana S.Conventional methods for synthesizing metallic nanoparticles face challenges such as instability and environmental concerns. Therefore, new, simpler, and more eco-friendly methods are being explored. In this context, the study reports a green synthesis process to produce magnetic iron oxide nanoparticles using an aqueous extract of the alga Chlorella vulgaris. This process leverages natural resources to create ...
