“…This is evident from the findings of a study performed by Deshamukhya et al. 86 where they considered two cases of heat transfer; the first case considering only natural convection while the second case was performed taking into account the radiative effects too along with convection. The results showed better heat transfer rates through the fin in case II when compared to case I.…”

The high-end devices, sophisticated gadgets, smart home appliances, superfast vehicles and aero engines of twenty-first century demand better heat removal for efficient functioning. Thus, with an aim to facilitate higher heat transfer from mechanical and electronic equipment, extensive research throughout the world has been going at a steady pace. One such achievement in the field of heat transfer is the introduction of the porous fins. This paper aims to discuss the various important aspects of porous fins along with the noteworthy research and developments in this field over the last decade. The review starts with a brief idea of heat transfer mechanism through porous media followed by some discussion on the thermal analysis of porous fins. Usually, the complicated nonlinear energy equations of porous fins require analytical techniques along with numerical analysis to solve the same. A good number of relevant research works have been cited to understand the optimum shaping and derivation of governing differential equations. Finally, a strengths, weakness, opportunities and threats analysis has been done to analyze the various aspects of using a porous fin.

This work studied the geometric influence of height on the main flow parameters of a continuous food oven of the tunnel type of indirect heating.…”

Due to their greater flexibility in heating and high productivity, continuous tunnel-type ovens have become the best option for industrial processes. The geometric optimization of ovens to better take advantage of the heat transfer mechanisms by convection and thermal radiation is increasingly researched; with the search for designs that combine lower fuel consumption, greater efficiency and competitiveness, and lower costs. In this sense, this work studied the influence of height on heat exchanges by radiation and convection and other flow parameters to define the best geometric height for the real oven under study. From the dimensions and real operating conditions of continuous tunnel-type ovens were built five numerical models of parametric variation, which were simulated with the free and open-source software OpenFOAM®. The turbulent forced convection regime was characterized in all models. The use of greater heights in the ovens increased and intensified the recirculation regions, reduced the rates of heat transfer by thermal radiation, and reduced the losses of heat by convection. The order of magnitude of heat exchanges by radiation proved to be much higher than heat exchanges by convection, confirming the results of the main references in the technical-scientific literature. It was concluded that the use of ovens with a lower height provides significant increases in the thermal radiation heat transfer rates.

Robotic grasping has become one of the most important domains of robotics research over the past few decades due to its wide range of applications in industrial automation. The model of grasping objects by robot hand depends on a good number of factors, such as type and size of the object, the morphology of object, type of hand, degree of freedom, etc. Thus, the model sometimes becomes mathematically intractable. With the progress in computational capability, soft computing methods have found a way to address the challenges faced by traditional methods while dealing with the robotic grasping problem. This article aims to summarize the outcome of a systematic study in the field of application of soft computing methods in robotic grasping and manipulation. The key processes of robotic grasping where soft computing methods are applied are identified, and research contributions of all processes are analyzed. This review presents a state-of-the-art survey and attempts to find the research gaps in the area of soft computing applications to address the robotic grasping problem.
