The time that an absorption chiller needs to reach the designed working condition is called start-up. During this time, energy is consumed through the system while efficient refrigeration is not available. So, it’s too important to consider the influencing parameters on this period of time so that reduction in energy consumption is achieved. Also, ...

Design parameters for Bubble Column Reactors such as backmixing and light/dark cycles of microalgae cells are pertinent to transient flow dynamics and mesoscale coherent structures. Transient simulation is therefore of practical significance. Traditional CFD solvers are generally implemented on multi-core CPU workstations, which is time-consuming a...

BackgroundIndirect cooling method is an alternative scheme for magnetic alloy (MA)-loaded cavity because of the feasible structure and MA core treatment process. Stable and long-term operation is not possible without a powerful cooling system for the high-power MA cavity.PurposeThe paper reports a method to evaluate the cooling efficiency of an ind...

In this paper, bias-free operational uni-traveling-carrier photodiodes (UTC-PDs) for high-power pulsed millimeter-wave signal generation in the sub-terahertz regime are designed and investigated. The reliability of the physics-based transient simulation is first demonstrated by comparing with reported experimental results. Then, the epitaxial layer...

An in silico investigation of modelled Extracorporeal Life Support (ECLS) via a femoral arterial cannula revealed the existence of both a defined separation zone between the opposing flows (ECLS, native flow) and different ranges dependent on flow distribution. The interaction between pulsating native circulation and constant ECLS flow is dynamic. ...

In this paper, a study is conducted to quantify the impact of coating soil types on the energetic performance of an earth-air heat exchanger (EAHE). A new numerical modelling based on the finite element method and taking thermal properties of soils as inputs is first proposed. Afterwards, the model is validated with experimental measurements of tem...

The dynamics of air foil bearings (AFBs) are not yet fully captured by any model. The recent years have, however, seen promising results from nonlinear time domain models, and simultaneously coupled formulations are now available, avoiding the previous requirements for undesirably small time steps and temporal convergence studies.
In the present wor...
