    Interaction of Multi Nanoparticles in Flow of Hybrid Nanofluid over Disk Nanofluid is an important chemical fluid that is used in industries due to high heat transfer rates. Lately, a new kind of nanofluid is called hybrid nanofluid is used for further enhancement in heat transfer rate and is produced by two or more dissimilar nanomaterials [1]. Hybrid nanofluid show amazing thermo-physical properties that are not existed in the convective heat transfer fluids (water, oil etc.) and the nanofluids containing single nanomaterial. The main purpose of hybrid nanofluids is to achieve great enhancement in thermal or rheological properties. Moreover, the hybrid nanofluid is expected to achieve more thermal conductivity as compared to a single material nanofluids. In a continuation of achieving better thermal conductivity and thermal performs through single nano-material, many studies have been done [2-4]. In an extension of nanofluid research, few papers have recently discussed the topic on thermal performance of hybrid nanofluids [5-7] and found a deficiency in agreement among their results. In addition, there is deficiency of theoretical models that can guess the exact thermal performance as well as fluid flow characteristic of these fluids. Thus, it is needed to be focused on theoretical modeling of hybrid nanofluid flow along with effective physical properties to measure better understanding of its heat and mass flow the behavior. In this study, to analyses theoretically heat and mass flow behavior, the physical problems will be modeled through equations of continuity, momentum and energy which base on different conservation laws of physics. For physical properties, we will product mathematical co-relational models by different theories. So, by solving these equations with effective physical properties, we will obtain results for velocity and temperature profiles. These results will be used also in further physical quantities of engineering. In addition, disk shaped bodies are often used in automobile and chemical industries etc. For examples, it is used for rotating heat exchangers, bio-fluids production applications and in tubular membrane system etc. So, it is also important to discuss about configuration of geometry when such fluid flow over it.
