Baryon number density perturbations offer a possible route to experimentallymeasure baryon number susceptibilities and heat conductivity of the quark gluonplasma. We study the fluid dynamical evolution of local and event-by-eventfluctuations of baryon number density, flow velocity and energy density on topof a (generalized) Bjorken expansion. To that end we use abackground-fluctuation splitting and a Bessel-Fourier decomposition for thefluctuating part of the fluid dynamical fields with respect to the azimuthalangle, the radius in the transverse plane and rapidity. We examine how the timeevolution of linear perturbations depends on the equation of state as well ason shear viscosity, bulk viscosity and heat conductivity for modes withdifferent azimuthal, radial and rapidity wave numbers. Finally we discuss howthis information is accessible to experiments in terms of the transverse andrapidity dependence of correlation functions for baryonic particles in highenergy nuclear collisions.
