Abstract
The potential based BEM Morino variant is compared with a modified ver-
sion of the velocity based method proposed by Hess, on the calculation of
potential flow around 2-dimensional foils. In the Morino method, several
numerical implementations of the Kutta condition are investigated. The
test cases for the comparison of the two methods are analytical foils ob-
tained by conformal mapping techniques: Joukowski and Karman-Trefftz.
Surface solutions are presented and the main drawbacks and advantages for
each formulation are discussed. A verification study performed for the two
test cases reveals the existence of difficulties for the Morino method in foils
with a cusped trailing edge.
