“…With the expanded uncertainty U = kδ mic , a certain percentage of |δ δ δ| should be smaller than U. Timmins et al (2012) referred to this as the 'uncertainty effectiveness.' Assuming a Gaussian distribution, a 68.3 % confidence level is obtained when k = 1 and 95 % when k = 1.96 (Coleman and Steele 2009).…”

“…O método a posteriori de superficie de incerteza (uncertainty surface -US) desenvolvido por Timmins et al (2012) analisa as imagens gravadas investigando os parâmetros (diâmetro de imagem de partícula, concentração de traçador, deslocamento de imagem de partícula e cisalhamento) que influenciam no erro. Simulações Monte Carlo baseadas em imagens sintéticas foram utilizadas para esse propósito.…”

“…Uma vez que a incerteza PIV depende do algorítmo (configuração) utilizado, a resposta do algoritmo para a variação de magnitude de cada fonte de erro deve ser sistematicamente testada para gerar uma superfície de incerteza para esse algoritmo. A superfície de incerteza é gerada para cada campo instantâneo de velocidade (TIMMINS et al, 2012;SCIACCHITANO et al, 2014;SCIACCHITANO et al, 2015).…”

Declaration of authorshipI hereby confirm that the submitted work is entirely my own and was written only with help of referenced literature. iv AbstractSynthetic and continuous jets impinging onto an heated circular cylinder were investigated.The study was performed experimentally. For this reason, a piezoelectrically driven actuator with water as the working fluid was designed. The basic parameters of the experiments were: the slot nozzle width was 0.36 mm, the aspect ratio of the slot was 111, the cylinder diameter was 1.2 mm, and the cylinder-to-nozzle spacing related to the slot width was 5-21.
