Theoretical analysis and parametric investigation of an innovative helical air gap membrane desalination system

Abstract A helical air gap membrane desalination (HAGMD) system is designed in the present study.The condenser is designed as a cylindrical shape with helical fins machined on the outer surface of a hollow copper condenser.A detailed theoretical model, studying heat and mass transfer in the HAGMD module, was developed.The theoretical model for a cy
