   Master-uppsats,

   Författare :Raghu Lakshman Gundra; Jagadeesh reddy Medapati; [2021]
   Nyckelord :CFD anlysis; Heat exchangers; Heat transfer analysis; Heat equation temperature; Temperature equilibrium.;

   Sammanfattning : A heat exchanger is a device used to transfer thermal energy between two or more fluids, at different temperatures in thermal contact. They are widely used in aerospace, chemical industries, power plants, refineries, HVAC refrigeration, and in many industries. LÄS MER

5. 14. Optimizing Control Algorithm for Indirect Liquid ThermalManagement of Batteries : A Study Executed at Northvolt

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Mantas Petrosius; [2021]
   Nyckelord :;

   Sammanfattning : The vast expansion of intermittent sustainable energy generation has favoured a gradual adoption of lithium-ion batteries in various industrial and automotive applications. Despite its many inherent merits, this storage technology is very vulnerable to temperature variations: the performance and lifespan of LIBs are substantially influenced by their load cycles, thermal behaviours, and operating temperature range.
