Heat transfer study influenced by various physical effects like thermal radiations, convective heat condition and thermal slip is one of the influential research domain specifically in applied thermal and chemical engineering. Therefore, the key purpose of this is to develop and discuss the heat performance of ternary nanofluid model including the effects of above mentioned parameters. The model is developed for laminar flow of ternary nanofluid about stagnation point over a cylinder's surface. Use of similarity transforms, properties of ternary nanofluids and ternary particles are exercised to obtain final model. Then, the RK-scheme is implemented for demonstration of the physical results and provided a detailed discussion. It is noticed that for λ=0.1,0.2,0.3,0.4, the ternary nanoliquid movement boosted and for λ=−0.1,−0.2,−0.3,−0.4 control the motion and MBLT (Momentum Boundary Layer Thickness) diminishes for saddle point case. Increasing the transient effects A1=0.05,0.10,0.15,0.20 causes quite rapid movement of the fluid molecules. Further, it is observed that thermal slip (α1=0.1,0.2,0.3,0.4), surface convection Bi=0.1,0.2,0.3,0.4 and thermal radiations are good physical aspects to enhance the heat transfer. Also, decrease in thermal boundary layer is observed. For composite φ=2.0%, density increases as 105 %(nano), 129 %(hybrid), 145 %(ternary), dynamic viscosity 105.18 %(nano), 113.503 %(hybrid), 122.483 %(ternary), thermal conductivity 106 %(nano), 115.5 %(hybrid), 131.71 %(ternary) and heat capacity diminishes.
