Abstract

In recent years, due to the rapid increase in the number of vehicles in the world, the traditional vehicles using gasoline or diesel as energy have led to serious air pollution and energy depletion. It is urgent to develop practical clean energy vehicles. The performance of electric vehicle depends on the power battery pack. The working temperature of the battery pack has a great impact on the performance of the battery, so it is necessary to carry out thermal management on the battery pack. Taking a lithium-ion battery as the research object, the temperature field of the battery pack in the charge and discharge state is simulated and analyzed by using CFD simulation software in the way of air cooled heat dissipation, so as to understand the influencing factors of uneven temperature field. At the same time, the development trend of battery temperature can be well predicted through simulation, so as to provide theoretical basis for the design of battery pack.

Impact of Polymer Coating on the Flexural Strength and Deflection Characteristics of Fiber-Reinforced Concrete Beams DOI:  https://doi.org/10.30564/jbms.v4i2.5304 Abstract Liquid polymers (LP) have become an important structural material used in the construction industry in the last decade. This paper investigates the viability of using commercially available LPs as a coating material to improve the flexural strength of fiber-modified concrete beams. The scope included preparing rectangular prism concrete beams with a concrete mixture including fly ash and fiber and coating them with four different liquid polymers at a uniform thickness following the curing process while one set of samples was maintained under the same conditions as a control group without coating. In addition, cylindrical samples were prepared to determine the compressive strength of the concrete mixture. Following the curing process in an unconfined open-air laboratory environment for another 28 days, concrete sa...
