Item type:Publication, Design and experimental analysis of an improved burner with natural gas(Springer Science and Business Media B.V., 2021-06-01)This research aimed to improve the thermal performance of industrial cookstoves using natural gas in Metropolitan Lima to promote good use of energy and reduce the impacts of climate change. The methodology was to use an appropriate test bench under the international standards of fuel gases; the appropriate instrumentation was used to record the variables such as temperature, pressure, mass flow, and relative air humidity. The burner was installed in the prototype cookstove and test bench to perform the experimental part. After that, the powers and performances of several industrial cookstoves in the Peruvian market were determined for comparison with the design of the prototype cookstove following the experimental methodology of 02 international standards, one Latin American and one Asian. The burner designed and manufactured in previous research gave a wide range of natural gas power according to the working pressure used and high efficiency of approximately 57% compared to the cookstoves that are sold nationwide, which on average is 53%. The advantage of this prototype cookstove is that it uses operating pressures between 23 and 34 mbar compared to stoves in the Peruvian market that do not have a standard of the maximum gas pressure. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Energy design and experimental evaluation of an industrial burner to natural gas(European Association for the Development of Renewable Energy, Environment and Power Quality (EA4EPQ), 2021-09-01)This research is focused on the design and experimental evaluation of a high-power industrial burner supplied by natural gas at an operating pressure of 23 mbar, based on improving thermal efficiency with a variation in geometric parameters. The specific objectives of the work were the following: Define the calculation procedure to establish the geometric characteristics of the burner, determine the thermal efficiency define a test procedure for the tests of thermal efficiency and finally analyse the data obtained from the power, thermal efficiency, and fuel consumption of the designed burners. This investigation will be preliminarily presented for a three-part burner. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Sensores/actuadores inteligentes basados en nanoestructuras amorfas para mejorar la transferencia de energía en brazos robóticos(Universidad Nacional de Colombia::will be referenced::ROR-ID, 2024-03-14)This article mainly analyzes the correlation between the carrier energy in robotic arms, according to enhance its performance. This task is achieved because of the sensors/actuators based on nanostructures properties: short response time and high robustness, which proportionated the possibility to execute intricate instructions by the control subsystem of the robotic arm. Therefore, the instructions executed by the controller are supported by a polynomial design, this algorithm helped to evaluate every response signal as a consequence of the main control system, which was consequently by the short response time from the main sensors “flow (carrier energy) and speed of the robotic arm”, moreover, the advantage of the proposed system is given by the extra time obtained also to verify the stability of the robotic arm based in Lyapunov models correlated with Lagrange, as well as every equations were solved and organized by neural network. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Experimental determination of a mixture composed of Camisea natural gas and CO2 laminar burning velocity(Multidisciplinary Digital Publishing Institute (MDPI), 2024-11-01)The aim of this work is to provide new experimental data on laminar burning velocities for a new synthetic mixture composed of Camisea natural gas and CO2. It was found that the relevant published experimental background data are limited to mixtures composed of methane and CO2; considering the fact that Camisea natural gas is widely used in Peru, this experimental research will serve as a supportive resource for further experimental and industrial implementations in this country, such as the design and modeling of new engines or industrial burners that are designed to be fueled by this mixture. An experimental setup for analyzing three types of flame geometry, which is feasible to implement for a wide range of conditions, was built in PUCP PI0735 laboratory and all the measurements were obtained for a range of mixtures (0%, 21.2%, 28.5%, 38.9%, 50% CO2) and ratios from around 0.55 to 0.95 at atmospheric conditions. The laminar burning velocities results obtained were analyzed in groups based on %CO2. In addition, the experimental margin error was determined by considering all the sources. The following conclusions were reached: (1) The laminar burning velocity decreases with the increase in CO2 percentage in the mixture due to the CO2 decreasing the flame temperature effect. (2) The flat flame type provided the highest value of burning velocity for each group of CO2 percentage in which it appears. (3) The highest obtained laminar burning velocity value was 22.64 ± 0.15 cm/s, for a flat flame with a ratio of 0.72 and 29.98% of CO2, while the lowest obtained value was 6.78 ± 0.15 cm/s for a conical trunk flame with a ratio of 0.59 and 49.83% of CO2. (4) The highest evaluated CO2 percentage was 50.97% for a conical trunk flame with a ratio of 0.69 and a burning velocity value of 11.04.
