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...
An overview of the recent advances in pool boiling enhancement materials, struc...
Pereira, José; Souza, Reinaldo; Lima, Rui Alberto Madeira Macedo; Moreira, António; Moita, AnaThis review attempts to provide a comprehensive assessment of recent methodologies, structures, and devices for pool boiling heat transfer enhancement. Several enhancement approaches relating to the underlying fluid route and the capability to eliminate incipient boiling hysteresis, augment the nucleate boiling heat transfer coefficient, and improve the critical heat flux are assessed. Hence, this study address...
A review of novel heat transfer materials and fluids for aerospace applications
Nobrega, Glauco; Cardoso, Beatriz; Souza, Reinaldo; Pereira, José; Pontes, Pedro; Catarino, Susana Oliveira; Pinho, DianaThe issue of thermal control for space missions has been critical since the early space missions in the late 1950s. The demands in such environments are heightened, characterized by significant temperature variations and the need to manage substantial densities of heat. The current work offers a comprehensive survey of the innovative materials and thermal fluids employed in the aerospace technological area. In ...
Thermal conductivity of nanofluids: a review on prediction models, controversie...
Gonçalves, Inês; Souza, Reinaldo; Coutinho, Gonçalo; Miranda, João; Moita, Ana; Pereira, José Eduardo; Moreira, AntónioIn recent years, the nanofluids (NFs) have become the main candidates for improving or even replacing traditional heat transfer fluids. The possibility of NFs to be used in various technological applications, from renewable energies to nanomedicine, has made NFs and their thermal conductivity one of the most studied topics nowadays. Hence, this review presents an overview of the most important advances and cont...
