This is a call for papers of a Special Issue on “Heat Transfer in Engineering”. The advancements in research related to heat transfer has gathered much attention in recent decades following the quest for efficient thermal systems, interdisciplinary studies involving heat transfer, and energy research. Heat transfer, a fundamental transport phenomenon, has been considered one of the critical aspects for the development and advancement of many modern applications, including cooling, thermal systems which contain symmetry analysis, energy conservation and storage, and symmetry-preserving discretization of heat transfer in a complex turbulent flow. The objective of the Special Issue is to present recent advances as well as up-to-date progress in all areas of heat transfer in engineering and its influence on emerging technologies.
The broad topics of interest include, but not limited to, the following:
- Heat transfer and thermal phenomena at all scales (from nanoscale to macroscale)
- Thermal systems and thermal management systems
- Interdisciplinary study focusing on heat transfer
- Waste heat recovery and allied heat transfer applications
- Heat transfer in energy storage and energy conservation
- Experimental, numerical and analytical studies focusing on heat transfer and thermal phenomena
- Fundamental mechanism and practical applications of heat transfer in wide variety of processes

Abstract: The present study elaborates the suitability of artificial neural network (ANN) and adaptive neuro-fuzzy interface system (ANFIS) to predict the thermal performances of thermoelectric generator system for waste heat recovery. Six ANN models and seven ANFIS models are formulated by considering hot gas temperatures and voltage load conditions as the inputs to predict current, power and thermal efficiency of thermoelectric generator system. The ANN model with back-propagation algorithm, Lavenberg Marquardt variant, Tan-Sigmoidal transfer function and 25 number of hidden neurons is found optimum model to accurately predict current, power and thermal efficiency. For current, power and thermal efficiency, the ANFIS model with pi-5 or gauss-5 membership function is recommended as optimum model when the prediction accuracy is important while the ANFIS model with gbell-3 membership function is suggested as optimum model when the prediction cost plays a crucial role along with prediction accuracy. The proposed optimal ANN and ANFIS models present higher prediction accuracy than the coupled numerical approach.

Abstract: Internal short circuit in lithium-ion battery by penetrating element leads to exothermic behavior due to accumulated heat. In the present study, investigations are conducted on thermal behavior of LIR 2450 micro coin cell having the capacity of 120mAh with internal short circuit by penetrating element. The experimental coin cell discharge study was conducted and validated with numerical study within 6.8%. The effect of penetrating element size, location of penetrating element, state of charge, discharge rate and heat transfer co-efficient on maximum cell temperature, heat generation rate and response rate (dT/dt) are analyzed. The penetrating element radius of 0.5 mm, 1.0 mm, 1.5 mm, 2.0 mm, 2.5 mm, 3.0 mm and 3.5 mm are considered. The effect of initial state of charge (SOC) is considered with 100%, 75%, 50%, 25% and 0%. Three locations for penetrating element are considered with center, middle and on edge of coin cell radius. The different discharge rates of 1C, 2C, 3C, 4C and 5C are considered. The higher penetrating element size with location at center of coin cell with 100% SOC and 5C discharge rate showed maximum heat generation rate and maximum temperature of the coin cell. The study provides comprehensive insights on thermal behavior of lithium-ion cell during thermal abuse condition with internal short circuit by penetrating element.

Abstract: Low temperature freezing is used in various fields such as food storage, medical devices, semiconductor processing. The cascade refrigeration system is the most popular system which can stably reach the low temperature zone. In this study experimentally analyzed the thermal performance characteristics of the cascade refrigeration system under various conditions using R-404A/R-23 refrigerant, and analyzed the optimum operating conditions. The main results are summerized as follows. As the condensation temperature of the HTC (High Temperature Circuit) increased, the coefficient of performance of the HTC decreased and the coefficient of performance of the cold part cycle remained almost constant. As a result, overall COP tends to decrease, which is thought to be greatly affected by the HTC. As the condensation temperature of the LTC (Low temperature circuit) increased, the performance coefficient of the HTC did not change significantly, but the performance coefficient of the LTC tended to increase. As a result, overall COP tended to increase, indicating that it was greatly affected by the LTC. As the condensation temperature of the LTC increased, the performance coefficient of the HTC decreased and the performance coefficient of the LTC increased. As a result, the overall COP tends to decrease up to a certain LTC condensation temperature. Finally, the optimum operating conditions were conducted by experiment.
