Design, fabrication, and testing of a digitally controlled charcoal smoker – A capstone project

There are many smokers available in the market nowadays. The two popular options are either electric or charcoal heated, each with their own downfalls. This capstone project built and tested a self-monitoring smoker that uses the smoke from burnt charcoal box to smoke chicken or meat in a separate smoker chamber. The objective of this capstone project was to design, build and test a charcoal smoker that is capable of maintaining its smoker chamber at a constant temperature that would be set by the user. The temperature of the smoker was controlled by the air flow rate into and out of the chamber using dampers at the inlet and exhaust ports. The project tested three set temperatures: 200˚C, 215˚C, and 250˚C. The temperature was maintained as needed within some margin ±5˚C. This fluctuation was due to airflow dampers opening and closing. To demonstrate the performance of the smoker, a raw chicken was smoked for 3.5 hours and it was smoked as intended. The smoker took approximately eight minutes to reach 200˚C. The project was led by a team of three senior MET (mechanical engineering technology) students. The project revealed the high impact on the level of understanding of students. Students performance and project outcomes were assessed against ABET learning outcomes, such as (1) applying knowledge, techniques, and skills to engineering technology activities, (2) applying knowledge of mathematics, science, and engineering to engineering technology programs, (3) conducting tests, measurements, calibration and improving processes, (4) problem solving: ability to identify, formulate, and solve engineering problems, (5) teamwork and (6) effective communication: ability to communicate effectively.

CFD based flow and heat transfer analysis of various ribs in solar air heater duct by continuous ribs on absorber plate

This article is present for a detailed investigation of the design of solar air heater having rib roughness on the absorber plate by using the application of computational fluid dynamics (CFD). In this Solar air heater an absorber plate is made of ‘Al’ and roughened with transverse ribs due witch creates the turbulence in the flow of fluid (air) and increase the heat transfer from the absorber plate to the fluid. Quantity of heat transfer is depending on Nusselt number. Nusselt number depends on surface heat transfer coefficient ‘h’. Heat transfer coefficient is strongly depends on the relative roughness height (e). Here ANSYS FLUENT v 14.5 is used to simulate fluid flow through a conventional solar air heater.

A Review on CFD analysis of heat transfer in a pipe having different External fin profile

All the electronic components release heat during their operation which must be transferred to the surrounding and its proper and intended operation and to avoid the damage of the equipment. The main aim of extended surfaces is to limit the maximum temperature in the metallic walls. Hence increase the possibility of using the least refractory material and minimizing the material and processing cost. Generally, the extended surfaces (fins) are made up of the materials having high conductivity like aluminium. The heat transfer will depend on the geometry of the fin like length, thickness, cross sectional area, width, spacing between the fins and the operating parameters such as heat supplied to the device, material of the fin, orientation of the fins, temperature difference between the fin and surrounding, number of fins, fin array orientation etc.as the electronic devices and engines developed, heat generated from them increases and while the surface area of the electronic equipment decreases continuously.

CFD analysis of heat transfer in a pipe having different External fin profile

The heat transfer rate to a fluid flowing in pipe can be enhanced by the use of fins. This thesis concerned with computer simulation study of tube with different fins used to enhance their heat transfer performance subjected to natural convection heat transfer. In the present study the performance of a heated pipe having fins of various configurations using ANSYS 15.0 is analysed. The material under consideration is aluminium and the free stream fluid is air. Base width and height of the fin were kept constant for all the three types. The heat transfer rate from the fins and the overall heat transfer rate has been calculated and compared for various fin configurations. Also the overall heat transfer co-efficient has been found out. Temperature contours for various fin configuration has been plotted showing the convection loops formed around the heated pipe surface. After comparing it is shown that we can find that the best configuration for this type of convective heat transfer of a heated pipe is a trapezoidal fin as they have the highest total heat transfer rate.

A review on CFD based flow and heat transfer analysis of various ribs in solar air heater duct by continuous ribs on absorber plate

In order to improve performances, in terms of higher thermodynamic efficiency and power output for heat exchanging devices like solar air heaters, heat exchangers and machines like gas turbines, the study of heat transfer mechanism and fluid flow play a vital role. Thermal assessment of heat exchanging devices, computational fluid dynamics (CFD) approach has advantages over the cost effecting practical experiments. To understand the complete phenomenon of heat transfer, heat flow as well as fluid flow must be considered in numerical analysis. Hence, accurate numerical method turbulence model and equation solving approach are required to predict heat transfer behaviour.

Feature selection: A review

Feature selection is an important process in machine learning, whose goal is to find a small number of features by removing irrelevant and/or redundant features. The main idea of feature selection is to choose a subset of input variables by eliminating features with or no predictive information. Feature selection removes dimensionality reduction problem. It is best for high dimensional data. Feature selection methods can be divided into three classes. One of is filter methods and another one is wrapper method and the third one is embedded method. This is one of two ways of avoiding the curse of dimensionality. This work reviews several fundamental feature selection algorithms found in the literature.
