This research aims to assess the impact of a combination of corrugated and baffled surfaces on hydrothermal performance in a channel. At Reynold numbers (Re) ranging from 3800 to 5700 and heat flux ranging from 10 to 20 kW/m2, the study is carried out on three different types of corrugated amplitude (e) (2.5–3.75–5) mm, three different types of corrugated pitch (p) (10–20–30) mm, and three different types of channel height (H) (10–12.5–15) mm. The analyzing was done using CFD (k-∈ turbulence model. According to the compared with (SC) results, utilizing corrugated channel (CC) significantly improves the thermal enhancement ratio (En) by 2.65 times, but at the cost of 4.2 times increase in relative friction factor (Γ) and 1.62 times increase in hydrothermal performance factor (HPF) as maximum value.

摘要

This research aims to assess the impact of a combination of corrugated and baffled surfaces on hydrothermal performance in a channel. At Reynold numbers (Re) ranging from 3800 to 5700 and heat flux ranging from 10 to 20 kW/m2, the study is carried out on three different types of corrugated amplitude (e) (2.5–3.75–5) mm, three different types of corrugated pitch (p) (10–20–30) mm, and three different types of channel height (H) (10–12.5–15) mm. The analyzing was done using CFD (k-∈ turbulence model. According to the compared with (SC) results, utilizing corrugated channel (CC) significantly improves the thermal enhancement ratio (En) by 2.65 times, but at the cost of 4.2 times increase in relative friction factor (Γ) and 1.62 times increase in hydrothermal performance factor (HPF) as maximum value.
