Since the airflow inevitably expands and accelerates in the horizontal duct, a full pressure drop is generated in the flow direction, thereby forming thermal resistance. Heat conduction (thermal conductivity) is a heat transfer phenomenon in the medium without macroscopic motion, which can occur in ...
