真空乾燥は, 製薬業界や食品業界で, 湿った粉末から水や有機溶媒を除去するために頻繁に用いられる化学プロセスです. 真空乾燥システムを設計する際, エンジニアは製品の品質を高く維持しながら乾燥時間を最小限に抑えることを目指します. このモデルは, Nutsche 式フィルタードライヤーにおける真空乾燥を調査します. Nutsche 式フィルタードライヤーは, 湿ったケーキが充填された円筒形のドラムで構成されています. ケーキの上部は低圧のヘッドスペースにさらされ, 側壁と底壁は加熱流体にさらされます. 非常に低い圧力と高温で動作させることで, 液体の蒸発速度が増加し, ... 詳細を見る

This model shows how to simulate moisture redistribution inside a wall with capillary active interior insulation. The wall consists of three layers: brick, mortar and insulating material. At the beginning of simulation, there is a sudden change in vapor pressure and temperature at ... 詳細を見る

One of the most common reactors in the chemical industry, for use in heterogeneous catalytic processes, is the packed bed reactor. This type of reactor is used both in synthesis as well as in effluent treatment and catalytic combustion. The reactor consists in essence of a container ... 詳細を見る

This case shows how to simulate moisture transport in a homogeneous wall under isothermal conditions. With this assumption, an analytical solution can be calculated. The homogeneous layer is initialized in moisture balance. At the beginning of the simulation, the relative humidity of ... 詳細を見る

This tutorial shows how to simulate coupled heat and moisture transport in a wall. The wall is modeled considering an air flow between interior and exterior varying with time. The 1D model is the third benchmark test defined in HAMSTAD-WP2 Modeling for the validation of numerical ... 詳細を見る

This tutorial shows how to simulate coupled heat and moisture transport in a wall made of a load bearing and an insulation layer. Moisture and temperature conditions vary with time on both sides of the wall and rain loading is included. The 1D model is a benchmark test defined in ... 詳細を見る

These models use the Discrete Ordinates method (DOM) and P1 approximation to solve a 3D radiative transfer problem in an emitting, absorbing, and linear-anisotropic scattering finite cylindrical medium. Using the S6 quadrature of DOM leads to accurate results, which are needed in ... 詳細を見る

Polymer hydrogels consist of a crosslinked network of long-chained polymers that has imbibed a large number of solvent molecules. Such materials are used in many biomedical applications, such as targeted drug delivery, tissue engineering, and stimuli-sensitive actuators. This benchmark ... 詳細を見る

This model approximates 3D spherical transport using a 1D model. Many models of industrial-transport problems allow the assumption that the problem is spherically symmetric. This assumption is of great importance because it eliminates two space coordinates to result in a 1D problem that ... 詳細を見る

This model utilizes the thermoviscous acoustic interface in a sub-model to obtain detailed results for the transfer impedance of a perforated plate (including the thermal and viscous losses). The impedance is in turn used as an internal impedance in a pressure acoustic model of a ... 詳細を見る
