This computational fluid dynamics (CFD) simulation shows internal airflow through a curved intake duct or pipe assembly. As air enters through the flanged inlet, green streamlines transition into yellow and orange vectors, indicating a progressive increase in flow velocity along the central path. The color-coded trajectory visually highlights flow acceleration and vector orientation as the fluid navigates the geometry's severe bend. #nicheengineering #airflowducts #airflow #HVAC #housemusic
