The fundamental ideas of nanofluid, nanofluid models, hybrid nanofluid, ternary hybrid nanofluid, thermophysical properties, and the notion of fluid dynamics are covered in the book so that researchers and post-doctoral researchers can understand the topic. Stretching sheet, parallel plate, cone, and wedge problems are the three geometries that we have selected. The similarity equations(ordinary differential equations) are solved using the shooting scheme and RKF-45 method with the aid of algebraic tools like Maple and Matlab. The work examines and derives significant dimensionless parameters for thermal and velocity profiles.
