What is the optimal twisted pitch length for enhancing heat transfer in double pipe heat exchangers?

The optimal twisted pitch length for enhancing heat transfer in double pipe heat exchangers varies based on different studies. Research by Wang suggests that a smaller twist pitch length, such as 160 mm, offers higher Nusselt numbers and friction factors in square twisted tube heat exchangers. On the other hand, Ilikan's study indicates that a length ratio (LR) of 70% in twisted tapes provides an optimum combination of maximum heat transfer and minimum friction, outperforming completely filling the tube with twisted tape. Additionally, Salman et al. found that using a helical tape with a pitch of 11 cm resulted in the maximum enhancement in Nusselt number and convection heat transfer coefficient in a double pipe heat exchanger. Therefore, the optimal twisted pitch length for heat transfer enhancement depends on the specific geometry and conditions of the heat exchanger.What are motor oil properties?

Genetic Algorithm (GA) optimizes micro heat sinks by employing a multi-step process that iteratively improves the design parameters to enhance performance metrics such as thermal resistance, pumping power, and operational time. Initially, GA defines a population of potential solutions based on the design variables, such as geometric configurations, material properties, and flow conditions. Each solution within the population is evaluated using objective functions that measure performance aspects like thermal resistance, pumping power, and entropy generation rate. The optimization process involves the selection of the best-performing solutions to form a new generation, applying crossover and mutation operations to introduce variability and explore the design space. This evolutionary process is guided by the principles of survival of the fittest, ensuring that over successive generations, the population evolves towards optimal solutions. The use of Pareto optimality in multi-objective optimization helps in identifying solutions that offer the best trade-off between conflicting objectives, such as minimizing thermal resistance while also minimizing pumping power. GA's effectiveness in optimizing micro heat sinks is further enhanced by integrating it with other computational methods. For instance, coupling GA with finite volume-based CFD solvers or surrogate models allows for accurate evaluation of the thermal and fluid dynamics performance of each design iteration. Additionally, GA has been successfully applied to optimize the geometric parameters of microchannel heat sinks filled with porous media, demonstrating significant reductions in thermal resistance. Moreover, GA has been utilized in specialized applications, such as optimizing the configuration of phase-change material-based heat sinks for extended operational times, and in the design of heat sinks with complex features like porous layers and deflectors to minimize hot-spot temperatures under mass constraints.
