Download - Heated pipe

Installation

Please download this paper on the model, and NOTE that this PDF includes a small but important correction at Figure 3.

The boundary condition for the temperature may be either fixed temperature or fixed heat-flux.

If you already have a Fortran compiler, then you only need download the current version (link below), and unpack

 tar -xvvzf Openpipeflow-hp-x.xx.tgz

The Makefile has been set up for gfortran, but compile flags for several compilers are included: g95, gfortran, ifort, pathf90, pgf90.

Use of the Heated pipe codes is essentially the same as the 'standard' (isothermal) code. If you've not used the standard code before, see Getting_started, then try the Tutorial.

Notes on the Heated pipe version

This code will load state files from the 'standard' (isothermal) pipe code. It will assume that there is no perturbation to the base temperature, r^2; a turbulent flow will quickly mix this up.

Note that the base temperature r^2 is not the laminar temperature profile, and that 1-r^2 is no longer the laminar flow profile. To compute the laminar temperature and flow profiles, set i_K=i_M=1, so that only the mean mode k=m=0 is simulated. This will very quickly approach the laminar temperature and flow profiles.
