000014723 520__ $$2eng$$aThe effect of hot-wire spatial resolution on turbulence statistics and velocity spectra in a round turbulent jet is investigated. To quantify spatial resolution effects, measurements were taken using conventional hot-wires with different sensing lengths of l = 0.5 mm and 1 mm and compared to results from a nano-scale thermal anemometry probe (NSTAP). Significant impact of spatial resolution on the velocity fluctuations, ⟨u2 ⟩, and dissipation, ⟨!⟩, is found along the jet centreline. Correction functions for the fluctuating velocity and dissipation data acquired with the conventional hot-wires are proposed. Along the jet centreline, the corrections are functions of l/η, where η is the Kolmogorov length scale defined as η ≡ ν 3/4 /⟨!⟩1/4 .
