Abstract: The research work predominantly focuses on the theoretical study of analysis of non newtonian unsteady nano fluids using series solution scheme. This study elaborates the Bioconvection Model for Magneto Hydrodynamics Squeezing Nanofluid Flow with Heat and Mass Transfer Between Two Parallel Plates Containing Gyrotactic Microorganisms Under the Influence of Thermal Radiations, Dusty Casson Nanofluid Flow with Thermal Radiation Over a Permeable Exponentially Stretching Surface, Unsteady Squeezing Flow of Water Based Carbon Nanotubes in Permeable Parallel Channels. The elementary constitutive unsteady equations of velocity, temperature and concentration are modeled in the form of partial differential equations and converted to a system of ordinary differential equations by using appropriate similarity transformation with unsteady dimensionless parameters. An optimal approach (HAM) have been used to get appropriate results from the modeled problem. The convergence of HAM method has been identified numerically. The first chapter of this thesis contains the introduction, fluid, nano fluids, Non Newtonian Fluids, Squeezing Flow, Stretching Sheet, Magneto-hydrodynamic, Dusty fluid, Carbon nanotubes, Basic idea of ham. In Second chapter we literature and methodology. In third chapter we investigate the bioconvection magneto hydrodynamics (MHD) of nano fluid flow squeezed between two parallel plates. One of the plates is extended and the other is kept fixed. the water is taken as a base liquid since it is consider as a best liquid for microorganisms life. Thermophoresis and Brownian motion and their significance also influences Nano fluid model. the method of combination has also been numerically shown. Nusselt number, 3 Sherwood Number and skin friction variation and effects of these Numbers on Velocity, temperature and flocky mass and the density of motile microorganism profiles are checked. It is raising radiation due to temperature also increase the temperature of fluid layer specially at the in the layers of the boundaries thus the rate of cooling for nanofluid flow decrease due to this temperature rise. Variation in bioconvection parameters like in the case of injection and suction, bring variation in the density of mobile microorganism and was investigated. Along with this some parameters were graphically plotted and discussed e.g. Thermal radiation parameter (Rd), Squeezing parameter   , Thermophoresis parameter(Nt), Brownian motion parameter(Nb), Peclet parameter (Pe) , Prandtl number (Pr), Schmidt number(Sc), Levis number (Le), to comprehend the physical presentation of these parameters in order to get some conclusion through this research paper. Punjab University Journal of Mathematics (ISSN 1016-2526) Vol. 51(3) (2019) pp. 113-136. In fourth chapter of the flow of Casson fluid on permeable exponential stretching along with dust and liquid phase in the presence of thermal radiation. With the help of elementary coupled and non-linear variables, the equation mostly used for fluid velocity and thermal energy has been altered to some suitable differential equation. The effect of temperature, velocity and concentration on the different types of parameters like parameter of radiation (RD), parameter of dust particles mass concentration (𝛾), parameter of unsteadiness (S) and porosity (k), Volume fraction of dust particle (ɸ𝑑) and Nano particles (ɸ),were studied. The impact of Sherwood number, skin friction and Nusslet number has been outlined. Correlation is accommodated the approval of our outcomes with previous successful works and is found in proper settlement. It has been seen that liquid molecule connection is directly proportional to the temperature exchange rate and is in reversely proportional to wall friction. Moreover, with radiation parameter, the profile of dusty nano fluid is raised productively. Journal of Nanofluids (J. Nanofluids )8,(4) (2019) pp. 714–724. In fifth chapter we investigation of 3-D squeezing flows of carbon-nanotube CNTs in light of water in a pivoting disk with the base wall making permeable has been introduced. Walls are also keep permeable. Graphs are present to discuss the effect prominent physical factors on the speed and temperature. Moreover, for different relevant variables the values for coefficient of Nusselt number & skin-frictions are arranged in tabular form. The most significant after effect of this research work is to think about the diverse practices of developing variables on carbon nanotube (CNTs) in light of the water with change in squeezing variable and to realize the effects of these rising parameter.
