  In the coalescence events of binary neutron star (NS) or a black hole (BH)
and an NS, a BH hyperaccretion disk might be eventually formed. At very high
mass accretion rates, MeV neutrinos will be emitted from this disk, which is
called a neutrino-dominated accretion flow (NDAF). Neutrino annihilation in the
space out of the disk is energetic enough to launch ultrarelativistic jets to
power gamma-ray bursts. Moreover, vertical advection might exist in NDAFs,
which can generate the magnetic buoyancy bubbles to release gamma-ray photons.
In this paper, we visit the effects of the vertical advection in NDAFs on the
disk structure and gamma-ray and neutrino luminosities for different accretion
rates. Then we study the anisotropic emission of kilonovae and the following
gravitational waves (GWs) driven by the gamma-ray photons and neutrinos from
NDAFs. Comparing NDAFs without vertical advection, the neutrino luminosity and
GW strains slightly decrease for the case with vertical advection, and the
kilonovae will be brightened by the injected gamma-ray photons. The future
joint multimessenger observations might distinguish whether the vertical
advection exists in NDAFs or not after compact binary coalescences.
