Hayrullin, Aidar Experimental study of heat transfer in an in-line tube bundle under reciprocating pulsating cross-flow: effects of Prandtl number and waveform asymmetry Mendeley Data This dataset contains operating parameters, similarity criteria, and measurement uncertainties for 180 pulsating-flow experimental regimes conducted on an 8×8 in-line tube bundle (D = 10 mm, S_L/D = S_T/D = 1.3) with water as the working fluid. Experiments cover the parameter ranges Re = 1200-3400, Pr = 3.5-5.0, A/D = 5-15, f = 0.18-0.45 Hz, and duty cycle psi = 0.2-0.5. The dataset includes the Nusselt number under pulsating flow (Nu_p), the heat transfer enhancement ratio (Nu_p/Nu_st), derived similarity parameters (Strouhal number, Fourier number, combined parameter (A/D)St), and expanded measurement uncertainties at the 95% confidence level evaluated in accordance with the GUM framework. Full description of the experimental methodology and data reduction procedure is provided in the associated manuscript.
