However, their unique selection might not ensure the optimized search procedure that enables the algorithm to explore for a global optimal solution for the given optimization problem. Further, with this selection approach, the algorithm might suffer from the issues of getting stuck at local optima and premature convergence. To address these challenges, this paper proposes a new framework of the DE called fitness and collaborative information-driven DE (COLDE). In the COLDE, a novel mutation operator is proposed to strengthen the collaboration among elite and non-elite candidate solutions so that more promising offspring vectors can be generated. The scale factor parameters are adjusted according to the evolutionary state of candidate solutions engaged in the mutation operator, while the crossover operator is tuned based on the success rates of crossover parameters determined in the past evolutionary stage. Moreover, the population size is also reduced over the generations to discard the unfavorable candidate solutions. The validation of the proposed COLDE is conducted on the standard set of benchmark problems provided by the IEEE CEC2017 of real-parameter single-objective problems and eight real-world engineering optimization problems.

Evaluated under diverse shear rates (200–1200 s⁻<sup>1</sup>) and temperatures (40 °C, 60 °C, 80 °C, and 100 °C), these nanolubricants exhibited significant enhancements in viscosity and thermal stability.

At lower temperatures, hybrid ratios such as R2 and R1 delivered up to 40% viscosity improvement relative to the base oil, leveraging stable nanoparticle dispersion, while their effects diminished at higher temperatures due to nanoparticle aggregation.

Unfortunately, the demands analysis for EVRP are hardly addressed. In this work, the energy-saving demand is discussed and the energy-consuming model is proposed. Based on the strategy of time disturbance, integrating static and dynamic data, the EVRP process is modified into a three-stage routing planning to meet the dynamic customer demand. Furthermore, the energy-consuming model and its objective function to analyze the cost-saving demand are improved. In the optimized heuristic algorithm based on demand analysis, the Q-learning algorithm is used to obtain a high-quality initial population and the two-step genetic algorithm (GA) is proposed to optimize the routing. The first step of the two-step GA is to use improved GA to meet the energy-saving demand and the cost-saving demand, the second step is to use the traditional GA to complete the dynamic routing of the three-stage routing with the dynamic demand. Compared with the traditional GA, the combination of the Q-learning initialization and the two-step GA reduces 36.68% in energy consumption. The two-step GA can quickly output different dynamic routes for dynamic customer demand at different times. In cost-saving demand, the optimization curve of the two-step GA versus the traditional GA converges 4 times faster and saves 2.84% in cost.

Unlike conventional or uniform helical configurations, the new design increases the shell area coverage by coiled tube, significantly boosting the probability of bubble-coil interactions and enhancing disruption of the thermal boundary layer around the tube. In addition, the new coil geometry ensures that the mixing of the shell fluid due to bubble injection occurs effectively near the coil boundary, unforming the temperature in this zone, thereby reducing temperature polarisation and maximising the temperature gradient between the coil surface and surrounding fluid. To do so, initially, the heat transfer performance of the novel coil configuration was theoretically validated by comparing its heat transfer coefficient, expressed through the Nusselt number (Nu), with that of a conventional helical coil using an appropriate heat transfer correlation. The study further explored the influence of air injection, introduced as microbubbles on the shell side of the heat exchanger, across a broad spectrum of operating conditions.
