Among the various industrial unit operations involved with multi-phase systems, agitation of solid-liquid systems is quite commonly encountered such as catalytic reactions, drilling operation of oil well, sand transport in fractured reservoirs, etc. Although there are many industrial applications of solid-liquid mixture flows in technology, the available knowledge about particle flows is not complete due to the difficulties encountered in analyzing these complex systems.
Due to the variety of the parameters related to the solid-liquid mixture flow, there may be various conditions to be included in considering the influence of the variable related to the transportation of drill cuttings. The study of transportation drill cuttings is a case of engineering that is classified as multi-phase flow accompanying solid particle, fluid and gas.
The study of drill cuttings transportation ability can be divided into the dynamics of the particles within the fluid largely and can be divided into the dynamics of the particles within the fluid largely and can be divided into the specialty and action of the drilling irrigation. When an oil well is drilled, it is necessary to transport the cuttings up to the surface. To this end, drilling fluid is pumped through the center of drill pipe and back up to the surface through the annular gap between the drill pipe and the drilled hole. The flow up to the annulus might be laminar or it might be turbulent, depending on the situation. With the increase in use of deviated, highly deviated and long reach drilling,
