摘要:In the paper the effect was studied of the presence of helical elements, having the role of turbulence promoters, on heat transfer intensification in coaxial tube heat exchangers, with fluids flowing in laminar regime. The quantitative determination of heat transfer intensification in the presence of turbulence promoters placed inside the device inner tube, was performed by calculating, from the energy balance data, the total heat transfer coefficients and reporting the values obtained to the total coefficient values calculated in the absence of promoters.
