“…Cui et al studied the development ideas of coatings and discussed application adaptability. The coating films of pipelines are not only flat and smooth, but also owns low roughness and high gloss, which is significant for faster transportation of oil and gas and reducing the internal drag force [88,95]. ER-based materials have unique characteristics in terms of tensile strength, low shrinkage, high moisture, ease of cure, thermal stability, and so on, as well as versatility.…”

“…Standa studied the temperature effect on the pot life of a coating material [87]. AW-01 pipeline coating introduced by China showed promising enhanced flow data as 20.9 % and guarantees the excellent corrosion and bending resistance [88]. Generally, to ensure the better performance of coating, the coating temperature should be kept between 40 °C and 55 °C.…”

The developments and involved factors of mature passive drag reduction technologies, i.e., compliant coating, superhydrophobic surfaces, and epoxy coating, are reviewed. Alterations in critical Reynolds number are observed in the presence of passive drag reduction technologies. With the advancement in technology, numerical approaches are introduced to lower the cost and achieve better understanding of physical phenomena such as lowering energy, flow control, designing the surfaces of materials, and so on. Experimental results as well as numerical results are stated. The effects of factors like wetting, contact angle, contact angle hysteresis, roughness, pot life, and coating aging responsible for drag reduction are also briefly presented with numerical and experimental perspective analyses.
