Design Of Expanded Metal Meshes For Generation Of Turbulence In Shell-And-Tube Heat Exchangers For Industrial Applications

Control of turbulence through use of lattice meshes has been a main topic in fluid-dynamic literature since mid of last century. A specific class of lattice meshes, known as expanded metal meshes, EMS, has been proposed for baffles design in novel longitudinal flow heat exchanger technology for promotion of turbulence under limited pressure drops about two decades ago. Present investigation aims at developing a simple model for the design and optimization of suitable EMS geometry for its utilization as turbulence promoter in shell&tube heat exchangers for industrial applications. Novelty of approach relies on pressure drops based geometry design for improved functional product features.
