Aerodynamic forces that occur around the vehicle must be considered since it involves safety, ergonomic, and fuel consumption. To reduce fuel consumption, the vehicle should be built as aerodynamic as possible to minimize drag forces. The vehicle becomes unstable at high speed due to increasing lift force. To balance the vehicle at high speed, a downforce should be generated to keep the tires attached to the road surface. Each type of car has a various value of aerodynamic force due to its design, dimension, and cross-section area. The characteristics of streamflow around the car are discussed in this paper. This research simulated 2D sedan car YRS 4 Doors in the steady condition in various velocities, i.e. 23 m/s, 26 m/s, and 40 m/s. This simulation used the Quad Pave mesh model and run in k-Îµ implicit turbulence model. The characteristics could be observed from the qualitative and quantitative data. The quantitative data used as measurable data were Coefficient of Pressure (CP) and Drag Coefficient (CD).Â Quantitative data was shown to outline a better visual explanation of the streaming characteristic. The qualitative data used in this paper are path lines, velocity vectors, and contours. The high-velocity stream results in a low value of CP. When the fluid flowed at high speed through a surface, it had low pressure. The coefficient of drag in the high-speed car decreased as the free stream increased. The value of the coefficient of drag (Cd) from this research was app. 0.567.

Biogas is a gas produced from anaerobic activity or the fermentation of organic materials, including human waste, animal waste, and waste. Biogas from cow dung can be used as an alternative fuel. In this study, biogas is used as fuel with the addition of variations of NaOH, urea, and rumen to the modified gasoline generator set engine so that it can work to generate electricity. This research was conducted by experimenting with varying nutrients, namely NaOH, urea, and rumen. Besides that, variations in the electrical load are carrying out for 15, 20, 25, 30, 35, 40, and 45. This is intended to determine the performance of the electrical energy produced. From the test, it was found that the voltage and engine speed of the generator set tended to decrease for the addition of variations in the electric load. Meanwhile, current, power, torque, average adequate pressure, and total efficiency increase for all additional electric load variations. The results showed that the most incredible efficiency was using 43.57% NaOH nutrition. For the variation of Urea nutrition in biogas, obtained total efficiency of 42.16%. Meanwhile, rumen nutrition variation has the most negligible efficiency than other nutritional variations, 39.55%.

There are many important reviews about the flow characteristics in the body of the racing bike helmet caused by the relative motion of the air along the Trailing Edge shape. The lines formed in such a way in the speed field will form a streamline stream so that the lines are in line with the flow at each point in the flow field. Thus, the streamline will form a pattern of airflow around the helmet. This aerodynamic characteristic study was performed on time meter helmet body visualized numerically using Computational Fluid Dynamics (CFD) with Solid Work Flow Simulation software. With variation of Trailing Edge 25 mm, 75 mm, 125 mm. Urgency research about helm time trial is believed to provide information about the flow that occurred. The result shows that the drag coefficient reduction that occurs on the cut variation of 75 mm compared with other variations on the Reynolds number 1.16 x 105 of 0.395.

Simplify car models such as Ahmed body is commonly used in numerical simulation because the aerodynamic forces that occur around the car are well captured. Various conditions around Ahmed body models change aerodynamic condition around the vehicle. Behind Ahmed body model, 2 secondary flow vortices are formed, called the twin vortex. This study explains the effect of various inlet velocities to the aerodynamic forces around the car at various inlet velocities of 35 m / s, 40 m / s and 50 m / s. This research simulate the Ahmed body model in 2D steady with the realizable k-epsiloin turbulence model. The Ahmed body model used in this study has 30o slope angle. At inlet velocity of 40 m / s wake that is formed the smallest size. At the inlet condition 40 m / s fluid flow has enough energy to suppress the wake that forms on the twin vortex and produces a small wake. Fluid flow at the bottom of the vehicle tends to be stable and produces similar trandline at various velocity.
