Abstract
Described herein are devices, systems, and methods for analyzing multi-phase fluid flow profile and flow field distribution by utilizing heating wires and thermal sensing arrays to detect transient thermal response and generate a dynamic temperature profile. The thermal sensing arrays include a plurality of thermal sensors disposed linearly along the length of the array. The multi-point dynamic temperature profile is used to determine fluid rate, velocity, flow patterns, and flow field distribution.
