Sustainability of EHD drying technology: Energy and exergy analysis
Abstract
Electrohydrodynamic (EHD) drying is a novel drying technology with extremely low energy consumption. To understand the reason for energy-efficient drying, energy and exergy flows in the thermodynamic system were studied. The thermodynamic study revealed that drying efficiency is dependent on the air temperature. Energy analysis was conducted using the First Law, while exergy was evaluated based on the Second Law of thermodynamics. The drying efficiency was characterized by energy and exergy consumption in Joules per gram of evaporated water. From exergy analysis and experiments, we concluded that water evaporation in EHD drying is primarily driven by scavenging of thermal energy from the ambient environment. A comparative analysis showed the advantages of EHD compared to other sustainable drying technologies based on renewable energy sources.
