Write an article on Technical Comprehension in the Subject Area of Heat Transfer. It needs to be at least 1500 words. From the experimental data, the Nusselt number for the different frequencies and amplitude of the forced vibrations were determined. the Nusselt number for the vibrating fin when normalized to the stationary fin is affected by the buoyancy-driven flow velocity and vibration speed ratio. Park et al. proposed a correlation practical velocity of approximately 0-20, while vibration frequencies at 29-59 Hz.

Park et al. utilized the auto-power spectrum in the vibrating fins when in the absence of heat supplies were measured via feeding of the random signal into the shaker. The material’s lowest dominant peak frequency for each auto-power spectrum was in the first natural frequency for the fin. The material thermal performance, that is, for the vibrating fins was maximized via transformation of the frequency of the forced vibrations into coinciding with the natural frequency, therefore known as the resonant frequency. The experiment utilized different resonant frequencies for the four experimental tests on the fins.

The Nusselt number correlation was in good agreement with their experimental or practical data. the data had discrepancies of less than 10%. Their correlation was valid only for frequencies within the range of 29 &lt. f &lt. 59 Hz. Their results indicated good consistency between the experimental and the correlation data when the Rayleigh number was between 20,000 and 8000, and indicated the decrease in normalized Nusselt when the temperature difference is increased.

Heris et al. (2014) conducted an experimental study for the investigation of the effects emanating from the inclination angle towards the natural convection of nanofluids within a cubic cavity having a side size of approximately 10 cm in length. One of the cubic surfaces for the cavity is maintained in cold temperature while the other side, opposite side, was maintained in hot temperature and the remaining four surfaces were insulated. There existed mixtures of nanoparticles, three different types of the particles were utilised, for example TiO2, CuO, and Al2O3 within the turbine oil (the TO) were utilised as the heat transfer fluids.&nbsp.
