Abstract:
Convective heat transfer under the laminar flow $(Re = 60)$ of M20 oil and air heated to $333$ K around a circular cylinder with a wavy surface roughness is computed using multiblock computational technologies, which are implemented in package VP2/3 for solving the Navier–Stokes and energy equations as part of the procedure for adjusting pressure. It is shown that at a roughness depth of $1%$ in fractions of the cylinder diameter, the heat transfer from the surface in oil increases by $21%$, and the thermal–hydraulic performance grows by $17%$.
