Abstract EN
Heat transfer enhancement technology has the aim of developing more efficient systems as demanded in many applications.
An available passive method is represented by the employ of rough surfaces.
Transversal turbulators enhance the heat transfer rate by reducing the thermal resistance near surfaces, because of the improved local turbulence; on the other hand, higher losses are expected.
In this paper, a numerical investigation is carried out on turbulent water forced convection in a ribbed channel.
Its external walls are heated by a constant heat flux.
Several arrangements of ribs in terms of height, width, and shape are analyzed.
The aim is to find the optimal configuration in terms of high heat transfer coefficients and low losses.
The maximum average Nusselt numbers are evaluated for dimensionless pitches of 6, 8, and 10 according to the shape while the maximum friction factors are in the range of pitches from 8 to 10.
