Electric field effect on the heat transfer enhancement in a vertical rectangular microgrooves heat sink

Introduction of a novel electric field-based plate heat sink for heat transfer enhancement of thermal systems

“…Because of some unique advantages of using the EHD technique, it has been widely investigated for increasing heat transfer as a method. Some examples for the application of the EHD technique are cooling heat sink (Tang et al , 2020; Joppolo et al , 2012; Nourdanesh and Ranjbar (2022); Zhang et al , 2019; Wang et al , 2013; Fazlollahi and Alemrajabi, 2018), solar collectors and chimney (Nourdanesh et al , 2020; Haghighat et al , 2019), air-cooled photovoltaic/thermal systems (Golzari et al , 2018), solar air heater (Kasayapanand and Kiatsiriroat, 2006), condensation (Mohammadi et al , 2021; Sadek et al , 2010), single-phase and two-phase heat and mass transfer (Alamgholilou and Esmaeilzadeh, 2012; Lohrasbi et al , 2017), mixing (Jalaal et al , 2013), boiling (Nangle-Smith and Cotton, 2019; Nangle-Smith and Cotton, 2018), heat pump systems (Trommelmans and Berghmans, 1986), air conditioning systems (Ohadi, 1991), film cooling (Jafari et al , 2020; Li et al , 2021), drying (Iranshahi et al , 2020; Dolati et al , 2018), defrosting systems (Rijing et al , 2020; Malik et al , 2020) and others. Compact size, simple design, no moving parts, noiselessness and insignificant electricity consumption (Seyed-Yagoobi and Bryan, 1999) are the reasons for this wide attention.…”

“…Different researchers have applied the EHD technique for heat transfer enhancement in the heat sinks (Tang et al , 2020; Ramadhan et al , 2018; Wang et al , 2019). Tang et al (2020) experimentally investigated transferred heat in a rectangular microgrooves heat sink under a non-uniform electric field.…”

Tang et al (2020) experimentally investigated transferred heat in a rectangular microgrooves heat sink under a non-uniform electric field. Their study revealed that the pin electrode utilization could boost the heat transfer performances and reduce the surface temperature of microgrooves efficiently.…”

Heat transfer enhancement of Fe 3 O 4 ‐water nanofluid by the thermo‐magnetic convection and thermophorestic effect

“…Microchannel heat sink (MCHS) has been developing rapidly due to the continuously increase of heat flux in many microsystems, such as microelectronic systems, photovoltaic systems, and nuclear energy systems because the powers of such systems almost double every 3-5 years in recent two decades. 1,2 Disturbance of the flow in microchannel and destruction of the boundary layers are two key mechanisms to promote the thermal property of MCHS, for example, microchannel with pinfins, 3 various ribs, 4 various lugs, or/and ruts. 5,6 However, the development process of MCHS is seriously impeded due to the fabrication difficulty and the great pressure loss.…”

An experimental study on the cooling efficiency of magnetite–water nanofluid in a twisted tube exposed to a rotating magnetic field

“…The main problem is that making the device smaller and more efficient will increase the device's need for cooling, and as a result, researchers need to improve previous methods to increase heat transfer and find new and innovative methods. Methods provided by researchers to enhance the performance of thermal systems include the utilization of fins [1][2][3], turbulators [4][5][6], MF [7][8][9][10][11][12][13][14][15], electric field [16][17][18] and wavy surfaces [19][20][21]. In addition to these old and common methods, new methods such as the use of nanofluids (NFs) have also been introduced and are being developed.…”
