Some of the most prominent ones are heat exchangers, heat pipes, furnaces, etc. In this study, conjugate heat transfer has been examined in a pipe filled with a porous medium experiencing a constant external heat flux. Th e an al ysis is ba se d on a tw o- dimensional domain using a quasi-thermal equilibrium model. Effects of porosity, pore density, Reynold’s number and thermal conductivity of solid and fluid on the Nusselt number have been studied. Three types of porous foams based on the pore density have been chosen for the analysis: 10 PPI, 40 PPI and 60 PPI. The results have been generalized for use in a wide range of Newtonian fluids. Additionally, the pressure drops across the pipes fi ll ed wi th po ro us media have been studied as a function of pore density and Reynold’s number. Numerical results indicate augmented performance with porous foams of high pore densities. However, using a porous medium with higher pore density leads to higher pressure drop, thus needing pumping power. The computational model used in this manuscript predicts that Nusselt number is increased by 38.7 % with Reynold’s number < 10000, when the porous medium is changed from 10 PPI to 60 PPI. The numerical data presented in the manuscript supports the application of low porosity foam with low pore density to achieve better thermal transport at the cost of pressure drop.}, number={4}, journal={JOURNAL OF THERMAL ENGINEERING}, author={Banerjee, Abhisek and Paul, Diplina}, year={2022}, month={Jul}, pages={529–537} }

PMC is a modern technology where combustion occurs within voids of the solid porous matrix. Researchers worldwide have developed PMC technology for various applications: from classical fields like turbines, internal combustion engines, heat exchangers, oil and gas extraction devices to modern areas like food processors, thermoelectric generators, etc. Though the ability of PMC to internally regenerate heat makes it suitable for a wide range of applications, yet its development is challenged by bottlenecks in flame propagation, flammability limits, operating efficiency, etc. This study has compiled global PMC research for application in small-scale energy-efficient systems. Following the general background, fundamental and governing parameters modulating PMC are presented here. Numerous significant and recent developments in the fundamental challenge of flame stabilization in PMC are discussed. This review focuses on the research conducted so far in the field of porous medium combustion to enable its wide application. Finally, this review discusses the various challenges and scope of future research essential in the development of PMC technology.}, journal={ENERGY}, author={Banerjee, Abhisek and Paul, Diplina}, year={2021}, month={Apr} }

Two types of burners are considered: counterflow porous burner (CFB) and reciprocal counterflow porous burner (RCFB). The combustion of methane-air mixtures flowing through the porous media is modeled by solving steady state governing equations to obtain the flame temperature and species profiles. Formation of CO, NO, NO2, and NOx is studied in CFB and RCFB in a range of equivalence ratios from 0.3 to 1.0 and heat extraction temperatures from 300 to 1,300 K. The contribution of various NO formation mechanisms is comparatively analyzed and related to the NO generation predicted by a detailed chemistry mechanism. The effect of high temperature heat extraction on the formation of CO and NOx is analyzed. Numerical predictions indicate a constant monotonic decrease of NOx concentration with increasing temperature of energy extraction. The formation of CO is observed to follow the similar trend. For heat extraction at 1,300 K, simulations predicted 3.6 ppm of NOx and 3.9 ppm of CO for CFB and 4.1 ppm of NOx and 3.5 ppm of CO for RCFB when these burners are operated at an equivalence ratio of 0.7.}, journal={FRONTIERS IN CHEMISTRY}, author={Banerjee, Abhisek and Saveliev, Alexei}, year={2020}, month={Feb} }

The primary flame is a rich premixed flame in the porous medium. The flame is stabilized in the range of equivalence ratios from 1.1 to 1.7 using upstream heat extraction. The products of the primary flame are rich in the partial oxidation and reforming products such as CO, H2, and CH4. Due to the self-regulated heat losses from the flame the maximum flame temperature of the primary flame remains close to 1700 K. The rich-flame environment and low-flame temperatures limit NOx formation in the primary flame. The NOx emission index of the primary flame shows a maximum at the equivalence ratio of 1.1 and reduces for richer mixtures. The products of the primary flame are burned in the secondary nonpremixed flame. The products could be intercooled to reduce temperature and minimize NOx formation in the secondary nonpremixed flame. The emission index of the secondary flame increases with the equivalence ratio. Variation of combined emission index shows a minimum value at the equivalence ratio of 1.2. The trend remains consistent with the intercooling of the primary flame products.}, number={9}, journal={COMBUSTION SCIENCE AND TECHNOLOGY}, author={Banerjee, Abhisek and Kundu, Prithwish and Gnatenko, Vitaliy and Zelepouga, Serguei and Wagner, John and Chudnovsky, Yaroslav and Saveliev, Alexei}, year={2020}, month={Sep}, pages={1633–1649} }
