CFD simulation of refrigerated display cabinets

Detailed CFD Modelling of Open Refrigerated Display Cabinets

“…The numerical studies of ORDC developed by Cortella et al [15], and George and Buttsworth [41] consider this BC at 2/3 and 5/4, respectively, of the equipment width. Bhattacharjee and Loth [9] stated that this BC should be imposed far away from zone of interest in the computational domain, likewise at a distance of 40b, being b the air curtain width.…”

“…Although, due to specific characteristics of air curtains installed in ORDC, researchers carried out two-(2D) and three-(3D) dimensional computational fluid dynamics (CFD) parametric studies. Cortella et al [15] and Navaz et al [16] evaluated the influence of DAG velocity in thermal performance, quantifying the air infiltration through the frontal opening. Axell and Fahlén [17] developed a CFD-parametric study to evaluate the influence of air curtain height/width ratio and inlet velocity on the thermal performance.…”

A multidomain boundary element method for two equation turbulence models

“…In the first paper by authors [15] the stream vorticity formulation is used for some kind of algebraic large eddy simulation using finite element method. The papers by [16,17] use the stream vorticity formulation and two-equation turbulent model using control volume method.…”

“…(33) is transformed to the system of algebraic equations by applying the boundary conditions (15), the known function value u on the boundary G 1 and the known normal flux value vu=vn on G 2 (16)…”

Effects of Switch Door on Temperature Field in Cold Storage Based on Numerical Simulation

“…However, there still exist many problems in the designing of the cold storage. For example, unreasonable design can result in heterogeneous distribution of flow field and energy loss [1][2][3][4][5][6][7], especially when you open or close the door of cold storage, for there is relatively huge temperature difference inside and outside of the cold storage, which may generate various problems, such as frosting, increasing temperature in the cold storage, etc [8].In order to solve these problems, air curtains have been installed at the doors of many cold storages. However, no matter what measures will be applied, It is necessary to understand the flow field near the door of the cold storage so as to make the measures more effective.…”
