SINDA/FLUINT는


1960년대에 우주/항공 분야에 사용하기 위하여 개발되어 현재는 다양한 분야에 활용되고 있으며 NASA, Boeing, Lockheed Martin 에서 표준 툴로

사용되고 있습니다.


특히 상변화 문제에 대한 해석에 특화되어 있어 극저온 분야에서도 많은 활용이 되고 있으며 유한차분, 집중 파라미터 방법을 이용하여 복잡한 시스템에서의 유체 유동 모델링과 열전달 설계에 사용할 수 있는 프로그램입니다.


25개이상의 나라에서 항공, 전자, 석유화학, 생물의학 등의 광범위한 분야에서 사용되고 있으며 항공우주분야에서 수년간 증명된 열전달 및 유체유동의 설계/분석이 강점인 소프트웨어로서 설계과정을 빠르고 쉽게 할 뿐 아니라 복잡한 시스템에 대한 이해도를 높여 시간과 비용을 단축시켜 줍니다.


또한 다른 프로그램과의 호환성이 뛰어나서 이용자들은 원하는 기능을 선택하고, 정확성의 정도를 결정하며, 각자의 작업에 알맞게 직접 필요한

물성치를 입력하여 해석을 수행할 수 있습니다.

SINDA/FLUINT 해석사례

곡선형 요소 : 열 엔지니어를 위한 맞춤형 격자의 생성

Curved Elements: Custom-made for Thermal Engineers

May 2016 presentation of Curved Elements (CEs). CEs are super-parametric finite elements that accurately represent curved shapes without requiring so many nodes that a system-level transient analysis is untenable. Mass and surface area, contact, radiation, etc. are accurate, and tiny flat facets are avoided.

하루 동안의  VRFB 스택 내부 셀에 대한 해석

Day in the life of a VRFB (Vanadium Redox Flow Battery)

A cell within a VRFB stack over a day (10 minutes to solve on one PC core, using Thermal Desktop and FloCAD). A serpentine flow field is used for electrolyte distribution. 4A charge and 13.3A discharge rate. The top is the cathode, the bottom is the anode, opened for viewing like a clamshell. Membrane and electrode pads have been removed for visibility. 5 cc/s anolyte and catholyte flows into a 17 cell stack.

Compartments and Ports : 부분적으로 채워진 용기의 모델링

Compartments and Ports: Modeling Partially filled Vessels

This is a recording of a webinar presented in December 2015. It covers FloCAD features (new to V5.8) that are useful for modeling fuel tanks, steam drums and boilers, superconducting magnet cooling dewars, immersion-cooled electronics, etc.

오일에 빠지는 렌치의 급냉 해석

Hot wrench lowered into oil

No film boiling like the "wrench quench" with water. To make the video more interesting, we slowed the lowering rate down. Otherwise, it takes a while to cool down and it all cools at about the same rate. So it would be boring. With the low gradients, low resolution (few curved finite elements) are used.

물에 빠지는 렌치의 급냉 해석

Hot wrench lowered into water

The wrench is at 200C initially. Film boiling (no bubble or steam is shown) is responsible for the persistence of the hot section below the surface. The quenched part moves slowly up the wrench, with sharp gradients that require fine resolution (small finite elements).




선박 연료탱크의 연료 배출 해석

marine fuel tank draining, side view

Same model/case as the aft and bow views. This time the top and sides are present but semi-transparent. Pitch motions have been enabled (but roll is still suppressed, though you can see the fuel react to it). The bow is left, aft is to the right.


 


marine fuel tank draining, bow view

48 minute transient scenario in 2 minutes on a PC. Hot aft wall near the engine, cold bottom wall near the hull. We could post a video where the horizon holds still and the boat tosses around on the waves, but you'd need sea sickness pills first!


 


marine fuel tank draining, aft view

48 minute drain scenario in 2 minutes on a PC. Looks like CFD but isn't. Holes between baffles let air and fuel pass, but mixing is imperfect. A warm back wall near the engine, cold bottom wall near the hull.

LHP 해석 (루프 히트 파이프의 냉각 시작)

LHP Start-up, Horizontal Condenser


First 1000 seconds of start-up of a horizontal LHP (loop heat pipe) condenser. Separation of liquid and vapor in the compensation chamber allows a cold shock event, with power more than doubling

LHP 해석 (서모스텟 제어에 의한 냉각)

LHP Radiator "Breathing" due to Thermostatic Control

With a large attached mass, a loop heat pipe (LHP) can experience large swings in throughput power even with small changes in heating applied to the compensation chamber.

물 먹는 새 : Thermal Desktop을 이용하여 물마시는 새의 시뮬레이션 해석

Simulation of a Drinking Bird

A simulation of the thermal/fluid and rotary dynamics of the famous toy drinking bird. This was done using Thermal Desktop, TD Direct, and FloCAD. The time scale is real time. This is not CFD: the run times on a single PC core are about 10-15 minutes per minute of real time. The particular case shown is for 85% relative humidity in a 22.5C room. Different conditions can generate chaotic oscillations.

움직이는 구형 LNG 탱크의 연료 방출 해석

Draining a moving spherical LNG tank

The liquid surface is visible thanks to some cutting away of the finite elements of the wall.

열적 계층화된 액체 산소 탱크(LOX) 해석

Thermally Stratified Liquid Oxygen Tank

Fills, holds, pressurizes, then drains. During the hold phase, temperatures within each phase begin to stratify vertically despite the formation of secondary circulation (boundary layers).
