Abstract
Local gyrokinetic simulations, performed with the GENE code, are used to investigate the interaction between (negative) triangularity
$\delta$
and magnetic shear
$s$
, in both ion temperature gradient and trapped electron mode dominated plasmas. Magnetic shear turns out to influence in a non-trivial way the effect of negative triangularity. Also,
$\delta <0$
is found to lead to a reduction of fluxes when
$s>1$
but not anymore when shear is reduced. In certain parameter regimes, this effect can be inverted, up to obtaining higher fluxes when
$\delta <0$
with respect to its
$\delta >0$
counterpart.
