Sono ancora oggi le <\/span><b>turbine idroelettriche che garantiscono il rendimento pi\u00f9 alto e<\/b><span style=\"font-weight: 400;\"> vengono utilizzate soprattutto in alta quota nei pressi di bacini alpini. L\u2019acqua viene condotta a valle da lunghe tubature fino a giungere in appositi ugelli che la convogliano sulle pale della turbina Pelton aventi forma di due cucchiai appaiati.<\/span><\/p>\n<p><\/p>\n<h2><span style=\"font-weight: 400;\">Turbine Francis<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Le <\/span><b>Francis<\/b><span style=\"font-weight: 400;\"> sono <\/span><b>turbine idrauliche a reazione <\/b><span style=\"font-weight: 400;\">utilizzate dalla prima met\u00e0 del 1800.

Le turbine Francis sono dette turbine a flusso centripeto dato che l\u2019acqua raggiunge il rotore attraversando un condotto a chiocciola e lambendolo lateralmente. Il flusso viene poi indirizzato sulle pale dello stesso mediante un distributore.<\/span><\/p>\n<p><\/p>\n<h2><span style=\"font-weight: 400;\">Turbine Kaplan<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Le <\/span><b>turbine Kaplan<\/b><span style=\"font-weight: 400;\"> sono le pi\u00f9 <\/span><b>recenti<\/b><span style=\"font-weight: 400;\">, inventate da Viktor Kaplan agli inizi del 900.&nbsp; Si tratta di&nbsp; <\/span><b>turbine idroelettriche <\/b><span style=\"font-weight: 400;\">a reazione che possono operare su dislivelli relativamente piccoli, nell\u2019ordine di pochi metri, <\/span><b>in presenza di grandi portate di acqua<\/b><span style=\"font-weight: 400;\">.

Le parti pi\u00f9 soggette a questi fenomeni sono proprio le pale di qualsivoglia rotore.
