AbstractApart from the advancing technology, the ever-increasing fuel price is one of themajor reasons behind the demand to transform tractor-trailer trucks to moreaerodynamically efficient. While tractor-trailer trucks are being retailed with normalaerodynamic packages there is stiff sufficient room for improvements towards a moreaerodynamic package through the incorporation of aerodynamic add-on devices for thetruck. It is imperative to point out that tractor-trailers exhibit an elevated drag coefficientas compared to other vehicles as a result of their bluff-body shape. There are severaladd-ons that have been introduced in the past few decades to address the high dragcoefficient associated with tractor-trailers. The current research seeks to investigate theuse of aerodynamic calculations to determine the most efficient way to reduce theaerodynamic drag coefficient associated with the tractor-trailer.ApplicationOne way to reduce fuel consumptions in an automobile is through aerodynamicdrag reduction. As compared to other vehicles, track-trailers exhibit a higher dragcoefficient. This elevated drag coefficient is as a result of their bluff-body shape. It iscrucial to point out that tractor-trailer and trucks consume a considerable amount of fuelas a result of their elevated drag coefficient (Lanser, Ross & Kaufman, 1991).Consequently, there is sufficient room for improving fuel consumption through reductionof the vehicle’s aerodynamic drag coefficient.Aerodynamic computations can be used to investigate the most efficient designstrategy with a lot of emphasis on the aerodynamic drag reduction. Computational FluidDynamics can be utilized in form of Detached-Eddy simulation (DES) and Reynolds-
