Abstract: Ohmic heating, heat dissipation and Darcy Forchheimer porous medium effects on turbulence of oscillatory heat and mass transfer along inlet heated cone in aircraft turbine and jet engines are investigated current problem. Darcy Forchheimer porous medium is applied to control turbulence of fluid flow, heat transfer and mass rate along inlet cone in aircraft engines. The transient Casson nanofluid model is used to enhance the heat transfer and flow control over inlet cone in turbo-jet aircraft engine. The flow controlling parameters are generated for physical behavior of thermal and flow boundary layers. The oscillatory motion of nanofluid and oscillatory heat transfer, oscillatory mass distribution, steady heat-mass transportation over inlet cone are calculated using Stokes transformation, complex variables and primitive formulation. The numerical and graphical results are deduced using significant parametric values of controlling factors. Lorentz force, Forchheimer porosity factor, Eckert number, Ohmic heating, solar radiation, thermophoresis, and Casson material parameter are utilized for oscillatory and turbulence flow of heat and mass transfer. The 2D behavior of streamlines and isothermal lines over inlet cone is examined. The following parametric range of 0.0≤Mf≤4.0, 0.0≤Fr≤1.2, 0.0≤Jh≤3.0, 0.0≤Ec≤6.0, 0.0≤NT≤8.0, and 0.0≤Rd≤20.0 is applied to control turbulent heat and mass oscillations. The high flow of isotherms contour and streamlines is found for minor Lorentz, Forchheimer factor and large ohmic heating factor. Larger oscillating amplitude in fluid velocity and temperature-concentration variation is observed for each Forchheimer factor. Remarkable distribution in non-fluctuating heating magnitude and nanoparticle movement is observed for each solar radiating parameter. Prominent oscillating amplitude and turbulent fluctuation in heat and mass distribution is depicted for each Eckert, thermophoresis and Forchheimer parameters. The high rate of steady heat and mass transport is increased as radiating energy increases.
