“…Lack of optimum thermal comfort can adversely impact the ability of the driver to focus and stay concentrated while driving [ [13] , [14] , [15] ]. Thus, proper designing of tractor cabin and effectiveness of air-conditioning system are crucial determinants to ensure thermally comfortable environment [ [16] , [17] , [18] ]. In this regard, different types of air-conditioning systems have been proposed in the existing literature for agricultural applications [ [19] , [20] , [21] ].…”

“…In [35][36][37][38][39][40][41][42], the results of CFD analysis of thermal and hydrodynamic characteristics for various vehicles were presented, and optimization issues for various configurations and cab geometries were considered. Using numerical analysis based on CFD [43][44][45] makes it possible to obtain excellent results in modeling air flows, especially considering turbulence [46,47].…”

Ensuring comfortable climatic conditions for operators in the cabin of technological machines is an important scientific and technical task affecting operator health. This article implements numerical and analytical modeling of the thermal state of the vehicle cabin, considering external airflow and internal ventilation. A method for calculating the heat transfer coefficients of a multilayer cabin wall for internal and external air under conditions of forced convective heat exchange is proposed. The cabin is located in the external aerodynamic flow to consider the speed and direction of the wind, as well as the speed of traffic. Inside the cabin, the operation of the climate system is modeled as an incoming flow of a given temperature and flow rate. The fields of velocities, pressures, and temperatures are calculated by the method of computer hydrodynamics for the averaged Navier–Stokes equations and the energy equation using the turbulence model. To verify the model, the values of the obtained heat transfer coefficients were compared with three applied theories obtained from experimental data based on dimensionless complexes for averaged velocities and calculated by a numerical method. It is shown that the use of numerical simulation considering the external air domain makes it possible to obtain more accurate results from 5% to 75% compared to applied theories, particularly in areas with large velocity gradients. This method makes it possible to get more accurate values of the heat transfer coefficients than for averaged velocities.

“…However, the test cycle that is cited by the authors are for light duty diesel vehicles and it is not clear that transportation by agricultural tractors is subjected to any regulation at all. The aerodynamics of agricultural tractor will also provide for additional aspects such as air conditioning in the tractor cabin since previous works is done for stationary or quasi-stationary conditions (Oh et al 2020).…”

New generation agricultural tractors contribute to transportation by increased travel speeds. There is not any available aerodynamic data on authentic agricultural tractor form. On-road transportation by tractors is between 8 to 30% of their operational time. In this work, two agricultural tractors are modelled via computational uid dynamics for nine different speeds to determine aerodynamic resistances.Corresponding speeds are 10 to 80 km/h with 10 km/h increments and additionally 5 km/h. Reynolds number changes between 1.6×10 5 and 2.98×10 6 . The characteristic lengths are taken as the square root of the streamwise projected area of the tractor geometries. Aerodynamic forces exerted on the tractors change between 3 N to 746 N. The calculated drag coe cients are found as independent from Reynolds number and are 0.6 and 0.78 for the two different types of driver compartments. Constant speed travel scenarios are analysed. The approximated aerodynamic related fuel consumptions for one-hour changes between 0.002 to 8.28 lt/s which correspond to 0.001 to 5.76 kg/s carbon emission. A potential improvement in decreasing aerodynamic resistance about 20% is discussed by spatial data. Since the conducted work is being regarded as the rst instance in the literature, it is estimated that several consecutive reports will be triggered.
