Abstract

The electric vehicle (EV) industries have grown; in 2023 EV sales increased by more than 30% compared to 2022. The central issue of this industry is the battery because of the cost and environmental problems.  This makes efficient battery operation and condition imperative. The electric vehicle lithium-ion batteries are highly temperature-dependent for optimal performance and longevity. A cooling system is needed to maintain the temperature of the lithium-ion battery within the optimal temperature range. This study proposes nanofluid cooling based on Cellulose Nanocrystals (CNC) inside the wavy channel tube. Other fluid cooling, such as air and water, are compared. Three-dimensional (3D) transient simulation is performed by varying the cooling fluid and mass flow rate. On the other hand, experiments were conducted to validate the simulation's conformity to the battery module's temperature. The performance of the cooling fluid inside the wavy channel effectively keeps the battery heat dissipation and temperature uniformity. The nanofluid can maintain the temperature of the battery module at its optimal temperature (below 40°C), even with the lowest flow rate (5×10-4 kg/s).

Abstract

Clean and healthy air are major topics around the globe. It is because poor air quality hurts human health and is even responsible for the deaths of millions of people. This work develops exhaust pipes containing filters to reduce the pollutants emitted by motorcycles. There are three pollutant concentrations measured here: CO2, CO, and HC. The measurements were taken before and after the filter system so that the pollutant reduction could be calculated.  The maximum pollutant reduction of the filter system: 6.1 % of CO2, 8.0 % of CO, and 651.0 ppm of HC. The primary mechanism of this filter is the physical trapping of pollutants. When the gas flows through the exhaust pipe, the pollutants in the stream are attached to the filter due to direct contact. This change can be visually observed in the filter color, which darkens after use in the exhaust pipe. However, a limitation of this work is its short-term experiment, which lasted only five minutes, indicating a key area for future research. It is also necessary to have alternative filters that are sustainable and can work properly in high-temperature conditions.
