Abstract
The pressure drop (dP) and flow pattern are presented for two-phase flow in a helical micro-scale channel using an SS-304 tube of 1 mm diameter, having an equal coil pitch of 20 mm, and a coil pitch of 20 mm, all under constant surface heat flux situations. A flow visualization study was conducted, revealing various flow patterns, including bubbly flow, slug flow, churn flow, throat-annular flow, and annular flow. Additionally, the results demonstrated a higher pressure drop (dP) during churn flow in the channel.
