  We discuss nonconforming virtual element method for convection dominated
(diffusive coefficient is very small compared to convective coefficient and
reac- tion coefficient ) convection-diffusion-reaction equation using L^2
projection operator.In this paper we stabilize the stabilization terms using
same technique which is used for stabilization of symmetric part in VEM, where
T is an arbitrary element, and assume H^2(T) regularity on each element to
prove polynomial consistency where v_h is approximate solution.We have shown
that linear nonconforming VE is not convergent for convection dominated
convection-diffusion reaction problem and higher regu larity of f ,source term
is also needed for convergence analysis.The novelty of this paper is we
introduce a new SDFEM type nonconforming virtual element method for
convection-dominated convection diffusion reaction equation, and discuss the
computability issue using degrees of freedom of element without explicit
knowledge of basis functions of virtual element methods.The present framework
is stable in the limit of vanishing diffusion.
