Nusselt number (Nu), friction factor (f) and thermal performance factor (η) inside corrugated …

Numerical simulations of temperature distribution in an annular diffuser fitted with helical
screw-tape hub and pimpled hub are carried out in this work. Three twist ratios (Y/H) 4, 6 …

Heat distribution and flow behaviors in an annular diffuser with twisted rectangular hub have
been numerically simulated in the present work. The study is conducted with three different …

Heat distribution and flow behaviors in an annular diffuser with cylindrical hub equipped with
helical tape have been studied in the present work. Different helical tape pitch (Y)(20 mm, 30 …

A study is made to enhance the rate of velocity distribution in a conical diffuser. In this work,
a numerical analysis on screw tape inserts in a conical diffuser is presented. In the …

Temperature distribution investigation in a conical diffuser fitted with helical screw-tape with
and without center-rod is studied numerically. A helical screw-tape is inserted in the diffuser …
