Potential Flow about Airfoils with Boundary Layer Coupled One-Way

Pablo is a pedagogical low-speed airfoil analysis program
written in MATLAB. It uses a one way coupled inviscid + boundary
layer model.

The inviscid flow is solved using a Panel Method [1]. Three
different kinds of singularity distributions can be used. The
boundary layer equations use the inviscid flow velocity provided by
the panel method, but the effect of the boundary layer on the
inviscid flow is not taken into account, as in Panda [2]. The
boundary layer model is described in [3]. It uses Thwaites'
equations for the laminar part of the flow, and Head's equations
for the turbulent part. Michel's criterion is used to locate
transition. The drag coefficient is computed using the Squire-Young
formula.

I am including this program with the PDAS collection as there may be
someone with an interest in the computational procedure.
It used to be maintained by the folks at the
Pablo website.

Note added 6 September 2015:
The KTH website seems to no longer exist.
If you want a copy of the Matlab source code, you may
download it
from here.
This is my copy as of 2004.

Pablo was maintained by

KTH- The Royal Institute of Technology

Stockholm, Sweden

Pablo was programmed by Christian Wauquiez in 1999.
The KTH faculty adviser was
Arthur Rizzi (rizzi@flyg.kth.se ).
