Numerical investigation of shell-side heat transfer in helically coiled tube heat exchangers: morpho-hydrodynamic effects and a data-driven multivariable Nusselt-number surrogate

Purpose This paper aims to investigate shell-side convective heat transfer in a vertically oriented helically coiled tube heat exchanger (HCTHEX) and develop a multivariable within-domain surrogate for the shell-side Nusselt number under fluid-to-fluid operation. Design/methodolo...
