Abstract: This study aims to determine the characteristics of the pressure coefficient and fluid flow separation in a tandem minibus model using the Fluent 6.3.26 computational method and experimental testing in a wind tunnel. Pressure measurements are taken by installing 14 pressure taps connected to a manometer on a 1:40-scale minibus model. Tests were conducted at five different distances between minibuses in a series configuration at seven-speed levels. The results showed that at the highest speed tested, minimal flow separation occurred at a distance ratio of L/D = 0.455, with values of CP = -0.083 in the first minibus and CP = -0.250 in the second minibus. This configuration is identified as the optimal spacing to reduce aerodynamic disturbance in the tandem minibus system.
