This paper presents a recent procedure for recovering the shear flow curve in Couette rheometer from torque‐rotational velocity data. It is the purpose here to extend the previous works and to compare our predictions in shear flow curve recovery with previous solutions in shear rate determination. With this goal, synthetic and experimental data of yield stress materials in Couette system are presently investigated.
