Preface

EUROTHERM-2021 8th European Thermal-Sciences Conference 20-22 SEPTEMBER 2021, virtual conference Proceedings Editor: Pedro J. Coelho This conference volume contains the papers presented at the eighth European Thermal Sciences Conference (EUROTHERM 2021) held virtually on 20-22 September 2021 and accepted for the Proceedings published in the Journal of Physics: Conference Series. The European Thermal Sciences Conferences have been taking place since 1992. The present conference, originally scheduled for 2020 in Lisbon, Portugal, was postponed to 2021 and organized virtually due to the SARSCoV-2 pandemic. It follows successful conferences in Birmingham (1992. 2004), Rome (1996), Heidelberg (2000), Eindhoven (2008), Poitiers - Futuroscope (2012) and Krakow (2016). List of Acknowledgements, Local Organizing Committee, Scientific Advisory Committee are available in this pdf.

Thermal aspects of Oldroyd-B nanofluid over accelerated surface with variable thermal conductivity and modified diffusion theories

The growing interest in emerging nanotechnologies has led the scientists towards to investigate the interaction of nanoparticles with fluids. Current continuation endeavors the rheological analysis for the Oldroyd-B nanomaterial across periodically accelerated and heated surface. The interesting features of thermophoresis and Brownian motions are presented by following famous Buongiorno nanofluid model. Further, Cattaneo–Christov heat and mass flux expressions are exploited to determine the characteristics of thermal and mass diffusions. As a novelty, the variable thermal conductivity and heat absorption/generation consequences are also utilizing the energy equation. The flow model has been developed by using concerning boundary layer equations which are converted into dimensionless forms by using appropriate variables. The analytical solution of such transmuted equations is computed by using homotopy analytic method. Various physical parameters of interest are scrutinized through various graphs. The observations from analysis convey a declining change in nanofluid concentration and temperature with variation of thermal and solutal relaxation parameters, respectively. Moreover, thermophoresis parameter causes an enhancement of concentration profile while a retarded concentration profile results with increment of Schmidt number. The obtained theoretical results reflect significant applications in cooling and heating systems, thermal sciences, manufacturing processes, extrusion systems, enhancement of transport of energy and heat resources.
