Computational Fluid Dynamics Simulations of Nonlinear Sloshing in a Rotating Rectangular Tank Using the Level Set Method
Grotle, Erlend Liavåg; Bihs, Hans; Æsøy, Vilmar; Pedersen, Eilif (Journal article; Peer reviewed, 2018)In this paper, numerical simulations of nonlinear sloshing in rectangular tanks are presented. Model implementations in the open source software reef3d are tested, and the results are compared with experimental data from ... -
Dynamic modelling of the thermal response enhanced by sloshing in marine LNG fuel tanks
Grotle, Erlend Liavåg; Æsøy, Vilmar (Journal article; Peer reviewed, 2018)This paper investigates the thermal response in marine liquefied natural gas (LNG) fuel tanks by experiments and modelling. The aim of this work is to develop phenomenological models that can predict the rapid pressure ... -
Experimental and Numerical Investigation of Sloshing under Roll Excitation at Shallow Liquid Depths
Grotle, Erlend Liavåg; Bihs, Hans; Æsøy, Vilmar (Journal article; Peer reviewed, 2017)This paper investigates sloshing at shallow-liquid depths in a rectangular container by using experimental and numerical methods. A motion platform is used to perform a prescribed periodic rotational motion to excite the ... -
Modellering av NOx frå forbrenning
Grotle, Erlend Liavåg (Master thesis, 2008)Føremålet med denne oppgåva har vore å setje seg inn i modellering av turbulent forbrenning og nytte teori i praksis ved simulering med dataprogrammet SPIDER. Rett modellering er viktig sidan både turbulens og forbrenning ... -
Numerical Investigation of Sloshing under Roll Excitation at Shallow Liquid Depths and the Effect of Baffles
Kamath, Arun; Grotle, Erlend Liavåg; Bihs, Hans (Peer reviewed; Journal article, 2021)Sloshing is relevant in several applications like ship tanks, space and automotive industry and seiching in harbours. Due to the relationship between ship and sloshing motions and possibility of structural damage, it is ... -
Numerical Simulations of Sloshing and the Thermodynamic Response Due to Mixing
Grotle, Erlend Liavåg; Æsøy, Vilmar (Journal article; Peer reviewed, 2017)In this paper, we apply computational fluid dynamics (CFD) to study the thermodynamic response enhanced by sloshing inside liquefied natural gas (LNG) fuel tanks. An existing numerical solver provided by OpenFOAM is used ... -
Thermodynamic Response Enhanced by Sloshing in Marine LNG Fuel Tanks: Experimental Work and Numerical Modelling
Grotle, Erlend Liavåg (Doctoral theses at NTNU; 2018:87, Doctoral thesis, 2018)This thesis presents studies of sloshing and how it influences thermodynamic conditions in liquefied natural gas (LNG) fuel tanks. Liquid in a moving tank mixes more efficiently with the gas, which condenses and is followed ...
