The research on flow of fluids fuelled by rotating disk motion has been increasing, due to the development of machine technology. Inspired by this development, we examined the deposition of thermophoretic particles in the flow of hybrid nanofluid suspended by ferrite nanoparticles past an expansion/contraction moving disk with rotation. Estimated PDEs are converted to ODEs with consideration of the corresponding similarity transformations. The obtained nondimensional expressions are solved by a numerical process known as the Runge-Kutta Fehlberg fourth - fifth order (RKF-45 method) by adopting shooting technique. Behavioural studies of velocity, concentration and thermal profiles of various parameter values are assessed using graphs. Physical concern parameters such as, velocity of thermophoretic particle deposition and velocity of thermophoretic are also analyzed graphically. The result reveals that, speed of the disk movement in the upward direction escalates the tangential as well as radial velocity gradients and rise in values of thermophoretic coefficient and thermophoretic parameter declines the rate of mass transfer.
