|Title:||Response of a near-wall hot-wire anemometer for velocity measurements||Authors:||Khoo, B.C.
|Issue Date:||1997||Citation:||Khoo, B.C.,Chew, Y.T.,Lim, C.P. (1997). Response of a near-wall hot-wire anemometer for velocity measurements. American Society of Mechanical Engineers, Fluids Engineering Division (Publication) FED 12 : -. ScholarBank@NUS Repository.||Abstract:||A known near-wall fluctuating flow field was imposed on a marginally-elevated hot-wire probe to quantify its dynamic response. In this preliminary work, it is found that the dynamic response of a given near-wall hot-wire configuration is dependent on the amplitude of imposed velocity change of the fluctuating flow field. With a constant amplitude of imposed velocity change, the dynamic response of the hot wire is shown to decrease with smaller height (h) above the wall substrate. This is consistent with numerous previous studies on wall corrections of near-wall hot-wire measurements about the increase influence of wall effect with decreasing h.||Source Title:||American Society of Mechanical Engineers, Fluids Engineering Division (Publication) FED||URI:||http://scholarbank.nus.edu.sg/handle/10635/75073|
