“…Yusuf et al [34] investigated the potential of three microchannel reactor designs for biodiesel production with vegetable oil. The microchannel reactors were fabricated via laser etching on polymethyl methacrylate acrylic sheets with varying designs: (1) T-mixer, (2) Y-mixer and (3) Tesla-shaped.…”

“…Hence, this contributes to a lower conversion cost due to a reduced capital expenditure investment. Yusuf et al [34] reported the study of a novel Tesla-shaped microchannel reactor for the production of biodiesel. Three different shapes of microchannel reactor designs were comparatively investigated, namely the Y-shaped, T-shaped and the novel Tesla-shaped Yusuf et al [34] reported the study of a novel Tesla-shaped microchannel reactor for the production of biodiesel.…”

The depletion of fossil fuels, along with the environmental damages brought by their usage, calls for the development of a clean, sustainable and renewable source of energy. Biofuel, predominantly liquid biofuel such as biodiesel, is a promising alternative to fossil fuels, due to its compatible direct usage within the context of compression ignition engines. However, the industrial production of biodiesel is far from being energy and time efficient, which contributes to its high production cost. These inefficiencies are attributed to poor heat and mass transfer of the transesterification reaction. The utilisation of microchannel reactors is found to be excellent in escalating heat and mass transfer of the reactants, benefitting from their high surface area-to-volume ratio. The microchannel also intensifies the mixing of reactants via the reactor design, micromixers and the slug flow patterns within the reactor, thus enhancing the contact between reactants. Simulation studies have aided in the identification of mixing regimes within the microchannel reactors, induced by various reactor designs. In addition, microwave irradiation heating is found to enhance biodiesel production by localised superheating delivered directly to the reactants at a molecular level. This enables the reaction to begin much earlier, resulting in rapid biodiesel production. It is postulated that the synergy between microchannel reactors and microwave heating would catapult a pathway towards rapid and energy-efficient biodiesel production by enhancing heat and mass transfer between reactants.

“…Due to the short residence times and high conversions obtained in microreactors, this production has been explored with the use of such micromixers (Gojun et al, 2021;Laziz et al, 2020;Santana et al, 2016;Schwarz et al, 2013). For example, Yusuf et al (2022) experimentally evaluated six microreactors with T-and Yshaped entrance sections to measure biodiesel yield. These geometries achieved biodiesel yields higher than 93% for residence times less than 5s.…”

“…The arrangement in an entrance region of a micromixer influences the interaction between fluids. Traditional T-and Y-shaped micromixers have been commonly adopted as feeding regions, with subsequent innovative geometric structures to induce chaotic advection (Lobasov et al, 2018;Mashaei et al, 2020;Prakash et al, 2023;Tokas et al, 2021;Yusuf et al, 2022). For instance, Kurnia et al (2022) proposed a traditional T-shaped micromixer with a twisted mixing channel to induce swirling secondary streamlines.…”
