Heat and mass transfer characteristics during spray drying of Na2Fe0.6Mn0.4PO4F/C cathode material for Na-ion batteries

Production of MgAl/layered double hydroxide microspheres and investigation of the volumetric heat transfer coefficient in spray drying

“…This work used an inlet mass flow rate of 0.45 kg h −1 , 40 times lower than the flow rate in their work [ 27 ]. Rajasekar and Raja (2023) investigated the heat and mass transfer characteristics during the synthesis of the Na 2 Fe 0.6 Mn 0.4 PO 4 F/C catalyst through intermittent spray drying with an inlet mass flow rate varying between 3.50 and 6.95 kg h −1 , obtaining values between 1.5 e 3.5 W m −3 K −1 for the volumetric heat transfer coefficient [ 28 ].…”

“…The spray dryer is one of the industrial dryers that consume the most energy, and its efficiency is strongly linked to the heat transfer between the hot drying air and the atomized droplets. However, few articles in the literature experimentally evaluate the volumetric heat transfer coefficient in spray drying [ [25] , [26] , [27] , [28] , [29] ].…”
