    Abstract: The theoretical development of the complex fluid flows such as more than one obstacle with different shapes have great interest for scientists to understand flow phenomena and verify the model or approximate solution. The complex physical properties due to a uniform streaming motion past two fixed spheres is investigated having one with shear stres... Show More

    Abstract: To success the drilling operations, different criteria must be taken in account. One of the most important criterion is the design and performance of drilling fluids, which is greatly related to their rheological properties. Furthermore, it is crucial to study the rheological behavior of water-based drilling fluid based on bentonite/polymer. The cu... Show More
