摘要: Abstract In this research, entropy generation and forced convection heat transfer of Al2O3-water nanofluid in a exchanger equipped with helical twisted tape is investigated via Finite volume method. Influences height ratio (BR), pitch ratio(PR) Reynolds number (Re) on are reported. Suitable formula for provided. Results reveal that thermal decreases rise BR Re. Frictional augments ratio.
