Ensuring a safe transportation process is impossible without the use of complex systems for interval regulation of train traffic. In particular, such a system is a continuous automatic cab signaling (CACS) where signals are affected by various kinds of interference, leading to system failures. To reduce the number of system failures, the authors previously proposed a quadrature signal receiver of CACS (QSR of CACS). The article presents the methodology and results of an experimental study of the quality of the functioning of the QSR of CACS on records of real signals and interference. A simulation model of the test facility has been developed in the Simulink simulation environment. The study showed that the QSR of CACS provides reliable reception of CACS code signals with a low level of interference. However, it needs to apply additional measures in it to reduce the influence of impulse noise.

“…Since the proposed quadrature receiver currently does not exist physically, it is advisable to use the computer simulation method to assess the quality of its operation [5,6,15,16,17,18]. In this case, the experimental setup is virtual and is implemented on the basis of a personal computer and specialized software.…”

“…In all studied flows, it was shown that in terms of the presence of an MF and NP S , the velocity of fluid flow decreased, but, on the other hand, Nu had a direct relationship with MF. Han et al 17 numerically studied forced convection HT and entropy generation in a microchannel in the presence of an MF and concluded that Ha number improved the HT rate. Hussain et al 18 studied the convective HT in the presence of MF with hybrid NF (Al 2 O 3 -Cu-water) in a wavy channel.…”

Recently, a great amount of research was done on wavy conduits due to the importance of heat and flow transfer in wavy channels and conduits, and their special use in various industries. The improvement of heat transfer in these ducts attracted the attention of many researchers, and experimental and numerical studies are devoted. The effect of the presence of a porous medium and magnetic field on forced convection heat transfer and a nanofluid flow in a complex wave-shaped channel with a special boundary condition (Non-uniform with respect to location) was studied for the first time. For this purpose, the heat transfer of a nanofluid in a two-dimensional sinusoidal channel containing a porous medium in the attendance of a magnetic field was analyzed. First, the nanoparticles were optimized using the design of the experiment method, and then modeling was performed using selected optimal particles. To improve heat transfer in a sinusoidal channel, the factors like the injection of optimized nanoparticles, porous medium, and magnetic field usage were used. The equations were discretized using the Fluent software with a finite volume method. The validation of problem outcomes was done using experimental and numerical studies. Porous medium in four different Darcys (10−5, 10−4, 10−3, and 10−2), and applying magnetic fields in four different Hartman (0, 4, 7, and 10) were examined. The results show that the channel wave, and magnetic field intensity improved heat transfer. Furthermore, using a porous medium with high Darcy can increase the Nusselt number. Hence, in the same conditions (Re = 500, Ha = 10) with Darcy number increasing from 10−5 to 10−2, Nu becomes equal to 5.011. This proposed system is an industrial-utility system that can increase heat transfer efficiency.

“…Graphene nanoplatelets and water in a sinusoidal microchannel were used by 26 to study how discrete heat sources affect the heat transmission and the pressure drop. Heat transmission in functionalized multi-walled nanotubes and water nanofluid is investigated by 27 in relation to the impacts of adding trapezoidal ribs to microchannels. Similarly, 28 numerically investigated and utilized the FVM of the convection heat transport, radiation, and entropy generation (EGE) of nanofluids (NFs) in a two- and three-dimensional square enclosure.…”

This work explores the magneto-hydrodynamics (MHD) Jeffery–Hamel nanofluid flow between two rigid non-parallel plane walls with heat transfer by employing hybrid nanoparticles, especially Cu and Cu-Al$$_{2}$$ 2 O$$_{3}$$ 3 . Here the MHD nanofluid flow problem is extended with fuzzy volume fraction and heat transfer with diverse nanoparticles to cover the influence of thermal profiles with hybrid nanoparticles on the fuzzy velocity profiles. The nanoparticle volume fraction is described with a triangular fuzzy number ranging from 0 to $$5\%$$ 5 % . A novel double parametric form-based homotopy analysis approach is considered to study the fuzzy velocity and temperature profiles with hybrid nanoparticles in both convergent and divergent channel positions. Finally, the efficiency of the proposed method has been demonstrated by comparing it with the available results in a crisp environment for validation.
