摘要
The current study addresses the influence of thermo-elasto effects on performance parameters of the journal bearing lubricated with biodegradable nanolubricants. It is assumed that the non-Newtonian nature of the biodegradable nanolubricants follows the power law model. The analysis is done by simultaneous numerical solutions of the modified Reynolds equation, adiabatic energy equation, and the deformation equation. The finite difference method is adopted to solve the Reynolds and energy equations with suitable iterative scheme. Simulated results reveal that the deviation in performance parameters due to thermo-elasto effects is observed differently for different power law indexes. Moreover, biodegradable nanolubricants enhance the load carrying capacity and friction force, while the attitude angle and side leakage remain unchanged in comparison with the base biolubricant.
