  In this paper we briefly introduce the quantum methods for computations of
the drag coefficients for flows around a body, using the flows around a rigid
sphere as an example, and we aim for comparing the wake under quantized
environment and the classical computational strategies for finding the drag
force. This paper however doesn't provide discussion on the pressure
distribution over the surfaces of a spherical body and neither the analytical
solution for the flows around an airfoil due to the greatly limited
computational capacities and resources.
