Identifying and characterizing the mass outflows associated with low-mass protostars is challenging since the outflowing gas is deeply embedded and often characterized by velocities comparable to the cloud turbulence. In order to investigate the evolution of such outflows, we use self-gravitating, radiation-hydrodynamic simulations performed with the Adaptive Mesh Refinement code, Orion. We construct synthetic observations in 12CO in order to compare with recent observations and assess the effects of beam resolution and outflow orientation on inferred outflow properties. We find that the interaction between the outflows and the turbulent core envelopes produces significant asymmetry. In addition, the opening angle broadening with time in both the simulations and CO synthetic observations is similar to that of observed outflows.
