Effect of the electrode arrangements in a tube bank on the characteristic of electrohydrodynamic heat transfer enhancement: Low reynolds number

Enhancement in heat transfer using the electrohydrodynamic (EHD) technique is numerically examined in laminar forced convection across a tube bank with six different wire electrode arrangements. The electric field is generated by the wire electrodes charged with high DC voltages ranging from 7.5 to...

The value Nu/Nu0 of an aligned configuration increases from row to row and appears to be similar with that of a staggered configuration. 2014-08-29T09:29:15Z 2014-08-29T09:29:15Z 2002 Article 10655131 10.1080/10655130216024 JETRE http://www.scopus.com/inward/record.url?eid=2-s2.0-0036708839&partnerID=40&md5=5c42479922972cdf71c9d0d426175a8b http://cmuir.cmu.ac.th/handle/6653943832/1398 English
