A numerical methodology for calculating the rheological stresses based on drop shapes is developed. We use it to study the rheology of a dilute emulsion in steady shear as well as oscillating extensional flow at finite inertia. Inertia-induced morphological change of drops gives rise to abnormal rheological responses such as shear thickening and sign change of normal stresses in shear flow, and a negative elastic modulus in oscillating extensional flow.
