Cradle CFD to oprogramowanie do CFD (Computational fluid dynamics), które służy do symulacji numerycznych przepływu cieczy i gazów. Umożliwia ono analizowanie rozmaitych scenariuszy i warunków przepływu, co pozwala na dokładniejsze zrozumienie zachowania cieczy i gazów w różnych, specyficznych warunkach. Program Cradle to zintegrowane narzędzie symulacyjne, które charakteryzuje się wysoką niezawodnością i szybkością realizacji obliczeń, co czyni go doskonałym narzędziem wspomagania prac projektowych i rozwojowych produktu lub procesu.
Wszechstronny program do obliczeń i symulacji CFD
Dzięki temu, że obliczenia numeryczne umożliwiają wyznaczanie parametrów technicznych bez konieczności tworzenia fizycznego prototypu, narzędzia symulacyjne można wykorzystywać już w wczesnym etapie planowania rozwoju produktu, aby przeanalizować wstępne koncepcje projektowe.
Program do symulacji i obliczeń CFD – Cradle, może być również wykorzystywany do przewidywania parametrów produktów, w przypadku kiedy trudno jest wykonać pomiary eksperymentalne. Ponadto analizy numeryczne można wykorzystać do wizualizacji niewidocznego lub trudnego do eksperymentalnej wizualizacji przepływu i wymiany ciepła. Skutkuje to lepszym zrozumieniem analizowanych zagadnień inżynierskich, a jednocześnie zapewnia możliwość przekazania tej wiedzy osobom niebędącymi ekspertami.
Program Cradle do analiz aerodynamicznych
Aerodynamika jest ważną dziedziną projektowania i inżynierii, ponieważ ma bezpośrednie przełożenie na wydajność i bezpieczeństwo statków powietrznych, pojazdów lub budynków. Cradle CFD jest również programem do analiz aerodynamicznych, który pozwala na symulację przepływu powietrza wokół różnych obiektów, takich jak samoloty, pojazdy, budynki czy turbiny wiatrowe. Cradle, program do analiz CFD, umożliwia określenie różnych wielkości aerodynamicznych, takich jak siły i momenty aerodynamiczne, pola ciśnienia, prędkości, temperatury, początek oderwania, wizualizacje olejowe, itd.
Pakiet oprogramowania Cradle CFD
Pakiet Cradle CFD – oprogramowanie do analiz CFD składa się z dwóch typów narzędzi do obliczeń cieplno-przepływowych:
scSTREAM i HeatDesigner z siatką kartezjańską (strukturalną)
Narzędzia scSTREAM i HeatDesigner służą przemysłowi elektronicznemu i architektonicznemu od ponad trzydziestu lat. Stale rozwijane oprogramowanie charakteryzuje się przyjaznym interfejsem użytkownika oraz dużą szybkością obliczeń i przetwarzania danych. HeatDesigner jest oparty na scSTREAM i został specjalnie opracowany do projektowania cieplnego produktów elektronicznych. HeatDesigner zapewnia funkcje fizyczne wymagane tylko w projektowaniu cieplnym, dzięki prostemu interfejsowi i dużej wydajności obliczeniowej.
Programy do analizy i symulacji przepływowych – CFD scSTREAM i HeatDesigner – przykładowe zastosowania:
- Projektowanie przepływu powietrza i wymiany ciepła w pomieszczeniach zamkniętych
- Aerodynamika małych prędkości, zarówno przepływy wewnętrzne, jak i zewnętrzne
- Analizy klimatyczne i urbanistyczne
- Projektowanie wymiany ciepła w elektronice i instrumentach precyzyjnych
- Ocena odporności elektroniki i przyrządów precyzyjnych na kurz i wilgoć
- Analizy przepływów wielofazowych, takich jak mieszanie, rozpylanie, krzepnięcie, topnienie, wrzenie i kondensacja
- Analizy z udziałem obiektów ruchomych, takich jak samochody, pociągi, urządzenia sterowane, urządzenia hydrauliczne i pneumatyczne oraz roboty
scFLOW i SC/Tetra z siatką niestrukturalną
SC/Tetra charakteryzuje się wydajną i szybką techniką generowania siatki, dużą wydajnością obliczeniową i przyjaznym dla użytkownika interfejsem. Zaawansowaną wersją jest program scFLOW. Jest on wyposażony w solver, który osiąga trzykrotnie większą szybkość obliczeń niż poprzednio, oraz nowy preprocesor, który pomaga początkującym użytkownikom budować skomplikowane modele z siatką wysokiej jakości. scFLOW jest oprogramowaniem nowej generacji, które stale się rozwija.
Programy do obliczeń i symulacji przepływowych CFD – scFLOW i SC/Tetra – przykładowe zastosowania:
- Symulacje aerodynamiczne statków powietrznych i pojazdów.
- Obliczenia maszyn wirnikowych, takich jak wentylatory i pompy.
- Obliczenia z uwzględnieniem kawitacji i erozji.
- Projektowanie urządzeń AGD, takich jak lodówki i pralki.
- Analizy przepływowe w różnego rodzaju kanałach, dyszach i zaworach.
- Analizy z uwzględnieniem reakcji chemicznych.
- Analizy zjawisk w przepływach wielofazowych, takich jak mieszanie, rozpylanie, krzepnięcie, topnienie, wrzenie i kondensacja.
scPOST
scPOST jest modułem programu Cradle CFD, który służy do analizy i wizualizacji wyników numerycznych symulacji przepływu. Pozwala on na importowanie wyników ze wszystkich pakietów oprogramowania Cradle CFD, a następnie przetwarzanie i analizowanie danych. scPOST umożliwia tworzenie różnego rodzaju wizualizacji, takich jak mapy ciśnienia, prędkości, temperatury, iso-powierzchnie, wyznaczenie linii prądu, jak również różnego rodzaju animacje.
Moduł umożliwia tworzenie wykresów i tabel, które pozwalają na analizę danych oraz tworzenie raportów zawierających wyniki analizy, co pozwala na łatwe przekazywanie informacji innym osobom. scPOST posiada także funkcje przetwarzania danych, takie jak filtrowanie, interpolacja czy redukcja wymiarów danych, co pozwala na jeszcze lepszą interpretację wyniku badań.
