The optimization of batteries has increased in EV and HEV applications out of which Li-ion batteries are widely used for green technology applications as an energy storage system due to its high power and energy density. In electric vehicle applications, drawbacks are observed during charging interval time on the storage system. In such situations, the multi-state charging is considered to be the ideal solution. This paper tells us about the state charging of lithium-ion battery and its criteria of charging/discharging for good battery life using MATLAB Simulink tool. The state-of-charge (SOC), measured and applied for measuring charging/discharging characteristics is an important parameter for defining the performance of a battery. Thus, accurate estimation of SOC is necessary which will protect the battery and prevent its overcharging and discharging. This will also help in improving the life span of the battery. For applications requiring higher efficiency, multi-state charging i...

Images of the lane given as an input to the algorithm, which will provide information about the lane and the Environmental condition which will be analysed by algorithm inorder to support the driver. The type of lane or the structure of the lane can be a type of information provided by algorithm. While Lane analysis the algorithm will completely ignore the useless information (such as surrounding area of lane or background) and will completely focus on the Lane. Only the lane lines will be the region of Interest in the LDS. The developed system can surely reduce the complexity of vision data and will meet the real time requirements. Based on the problems encountered in detecting objects by autonomous vehicles an effort has been made to demonstrate lane detection using Open CV library.

Abstract Smartphone's functional use is versatile in a modern-day application, which causes a prone in electronics performance; this is mainly due to gamming, high power camera applications, and increased usage of the internet. The continuous usage causes high power dissipation level in smartphones to increase by about 2–6 W. Depending on the scale of application, the cooling strategy is used in smartphones. In the present paper, a passive phase change material cooling strategy is proposed which can utilize the advantage of isotopic heat conduction from the electronic element. It changes its phase from solid to liquid to give an optimum cooling strategy over the electronic element which help in keeping the temperature of the electronic element below 85 °C. The economic mid-range customer segment smartphones are embedded with cooling strategy such as natural convection, indirect heat-pipe cooling and forced convection which typically fails for high power usage applications.

Abstract The present numerical investigation consists of a detailed evaluation of flow over the bluff body to determine its behavior of boundary layer flow separation around the surfaces. In the present study, square and rectangle shape bluff body is investigated for higher Reynolds number ranging from 63,651 to 636,505 with three different cases of the angle of inclination 0°,10°, and 20°. Optimize k– ∊ standard turbulent model with fine mesh grid is used to perform numerical investigation, and the results are validated from the literature in capturing flow separation from the surfaces. It is found that the flow separation regime behind the square and rectangular bluff body changes with Reynolds number and angle of inclination. It is also observed that the flow separation increases from the top side of the bluff body with an increase in the angle of inclination. The size and frequency of vortex generation increase with an increase in Reynolds number. A correlation is proposed for the vortex generation as a function of Reynolds number and angle of inclination. The prediction of vortices generation behind the square and rectangular bluff body is determined using the artificial neural network driven by CFD Data. A verification study is proposed in ANN approach based on neuron independent study to validate output field parameter of CFD.

Aerodynamic improvements primarily result in decreased fuel usage and carbon dioxide emissions into the atmosphere. Numerous governments support ongoing aerodynamics development initiatives as a means of addressing the energy problem and reducing air pollution, Ahmed body investigation helps research to investigate versatile approaches and flexibility of design. This study is carried over a generic design of Ahmed body model. We attempted a passive arrangement system to reduce drag coefficient with a correlation of cases such as in primary objective varying parameter of slant angle from 20∘ to 30∘ proposed to monitor the behavior of drag coefficient. Once we finalized the optimum slant angle, which gives a lower drag coefficient, the next proposed configuration is to vary passive arrangement between lower and upper blend length to see the deflection of the boundary layer in correlation with the drag coefficient. The final topology is selected, which gives the lowest drag coefficient...

In computational fluid dynamics (CFD), there is a transformation of methods over the years for building commercially coded software. Each method has predicted its own set of importance, but the exportation and prediction of data are some of the crucial elements for post-processing and validating results. In the present investigation, a detailed comparative analysis is performed over finite difference method (FDM) and finite volume method (FVM) method for the 1D steady-state heat conduction problem over a 1-m-long plate. The comparison was made between solution creation and validation between FDM and FVM for the analytical and computational scheme. The convergence-dependent study is performed as multi-objective optimization to predict how artificial neural network (ANN) can be used to verify and validate the solution of CFD.
