Time-dependent multiphysical simulation of pulsed and continuous laser welding of dissimilar metals, based on Moving Mesh (ALE) approach, is proposed. Strong coupling between heat transfer, laminar compressible flow and ALE is used. The model was validated for a case of single ... En savoir plus
The US Food and Drug Administration (FDA) faces significant challenges in its regulatory approval processes due to a lack of relevant science, and many practices are limited by laws enacted in the previous century [1]. Therefore, in recent years, the FDA has identified the need for ... En savoir plus
As the flow passed through the pipe, and entered the bend, various vortical structures appear, meaning that there is a secondary flow emerging. Also while the flow is in the bend gravity forces affect distinctively its behavior as long as the centrifugal force is not greater. From this ... En savoir plus
Microarrays are extensively used in modern biology as tools of multiplexed, high throughput analysis to study thousands of genes and their expression inside cells at once [1]. The basic principle of a microarray is quantitative detection of fluorophore tagged DNA. Use of this method ... En savoir plus
We show that COMSOL Multiphysics® software can efficiently simulate the diffusion equation (DE) in diffusive optical tomography systems. Using our implementation, we simulate a frequency domain diffusive optical tomography system two order of magnitude faster than the standard Monte ... En savoir plus
Single-phase fluid flow was simulated passing through various three dimensional pipe elbows. The simulations varied by Reynolds number, curvature ratios, and sweep angles and were all conducted using the k-ε model available in COMSOL Multiphysics® software. The intent of this research ...

Stimulated Brillouin scattering (SBS) is a nonlinear phenomenon coupling optical and elastic waves. Traditionally regarded as an undesirable side-effect, it has garnered renewed interest as a platform for investigating slow light, nonreciprocity, and for designing high-performance chip ...

Interstitial photodynamic therapy (I-PDT) can be applied for the treatment of locally advanced head and neck squamous cell carcinoma (LA-HNSCC). The complex anatomy of LA-HNSCC requires careful planning of the light delivery and fiber insertion. We have developed an image-based approach, ... En savoir plus
Mechanical product design is crucial in many engineering field and lots of industries. CAE simulation has been widely applied for predicting virtual product design for a few decades to reduce the cost and shorten the design life cycle. Because of complicated geometry, material ... En savoir plus
Oil-water separators play an important role in several industries as well as in waste water treatment. However, no basic principles have been set to guarantee the designed separators would work according to the desired efficiency due to the effect various factors. Both time and money ... En savoir plus
