I nanofluidi sono sospensioni di nanoparticelle nel fluido di base (acqua) che ne migliorano significativamente le propriet . stata condotta un'indagine per studiare l'analisi delle prestazioni dello scambiatore di calore a fascio tubiero utilizzando due tipi di nanofluidi: CeO2/acqua e CeO2 + MWCNT/acqua. I nanofluidi a base di acqua fredda scorrono nel lato tubi e l'acqua come fluido caldo scorre nel lato mantello. I risultati indicano che il nanofluido ibrido (90% ceria + 10% MWCNT) ha prestazioni di trasferimento di calore migliori (incorporano il tasso di trasferimento di calore, il coefficiente di trasferimento di calore convettivo, il coefficiente di trasferimento di calore convettivo complessivo, NTU e l'efficienza) rispetto al nanofluido CeO2/acqua (concentrazione in volume dello 0,75%).

Nanofluidy to zawiesina nanocząstek w plynie bazowym (wodzie), kt ra wykazuje znaczną poprawę ich wlaściwości. Przeprowadzono badanie w celu analizy wydajności plaszczowo-rurowego wymiennika ciepla przy użyciu dw ch rodzaj w nanofluid w, a mianowicie CeO2/woda i CeO2 + MWCNT/woda. Nanofluidy na bazie zimnej wody przeplywają po stronie rury, a woda jako gorący plyn przeplywa po stronie plaszcza. Wyniki wskazują, że nanofluid hybrydowy (90% keria + 10% MWCNT) ma lepszą wydajnośc wymiany ciepla (w tym szybkośc wymiany ciepla, konwekcyjny wsp lczynnik przenikania ciepla, og lny konwekcyjny wsp lczynnik przenikania ciepla, NTU i wydajnośc) w por wnaniu z nanofluidem CeO2/woda (stężenie objętościowe 0,75%).

Os nanofluidos s o suspens es de nanopart culas no fluido de base ( gua) que apresentam um aumento significativo das suas propriedades. Foi efectuada uma investiga o para estudar a an lise do desempenho do permutador de calor de casco e tubo utilizando dois tipos de nanofluidos, nomeadamente CeO2/ gua e CeO2 + MWCNT/ gua. Os nanofluidos base de gua fria fluem no lado do tubo e a gua como fluido quente flui no lado do casco. Os resultados indicam que o nanofluido h brido (90% c ria+10% MWCNT) tem um melhor desempenho em termos de transfer ncia de calor (incorporando a taxa de transfer ncia de calor, o coeficiente de transfer ncia de calor por convec o, o coeficiente global de transfer ncia de calor por convec o, o NTU e a efici ncia) em compara o com o nanofluido CeO2/ gua (0,75% de concentra o volum trica).

Les nanofluides sont des suspensions de nanoparticules dans le fluide de base (eau) qui am liorent consid rablement leurs propri t s. Une enqu te a t men e pour tudier l'analyse des performances d'un changeur de chaleur calandre et tube utilisant deux types de nanofluides, savoir CeO2/eau et CeO2 + MWCNT/eau. Les nanofluides base d'eau froide circulent du c t du tube et l'eau, en tant que fluide chaud, circule du c t de l'enveloppe. Les r sultats indiquent que le nanofluide hybride (90 % de c rium + 10 % de MWCNT) pr sente de meilleures performances de transfert de chaleur (taux de transfert de chaleur, coefficient de transfert de chaleur convectif, coefficient de transfert de chaleur convectif global, NTU et efficacit ) par rapport au nanofluide CeO2/eau (concentration volumique de 0,75 %).

Bei Nanofluiden handelt es sich um die Suspension von Nanopartikeln in der Basisfl ssigkeit (Wasser), die ihre Eigenschaften deutlich verbessern. Es wurde eine Untersuchung durchgef hrt, um die Leistungsanalyse eines Rohrb ndelw rmetauschers mit zwei Arten von Nanofluiden, n mlich CeO2/Wasser und CeO2 + MWCNT/Wasser, zu untersuchen. Die auf kaltem Wasser basierenden Nanofluide flie en auf der Rohrseite und Wasser als hei es Fluid flie t auf der Mantelseite. Die Ergebnisse zeigen, dass das Hybrid-Nanofluid (90 % Ceroxid + 10 % MWCNT) im Vergleich zum CeO2/Wasser-Nanofluid (0,75 % Volumenkonzentration) eine bessere W rme bertragungsleistung (W rme bertragungsrate, konvektiver W rme bergangskoeffizient, gesamter konvektiver W rme bergangskoeffizient, NTU und Effizienz) aufweist.

Nanofluids are the suspension of nanoparticles in the base fluid (water) that show significant enhancement of their properties. An investigation was carried out to study the performance analysis of shell and tube heat exchanger using two types of nanofluids namely CeO2/water and CeO2 + MWCNT/water. The cold water based nanofluids flow in tube side and water as hot fluid flows on shell side. Results indicate that hybrid nanofluid (90% ceria+10% MWCNT) has better heat transfer performance (incorporate the heat transfer rate, convective heat transfer coefficient, overall convective heat transfer coefficient, NTU and efficiency) compared to CeO2/water nanofluid (0.75% volume concentration).
