Flow stagnation and residence time (RT) are important features of diseased arterial flows that influence biochemical transport processes and thrombosis. RT calculation methods are classified into Eulerian and Lagrangian approaches where several measures have been proposed to quantify RT. Each of these methods has a different definition of RT, and i...
The growing interest in research of UAV, equipped with increased payload, shortened take-off and landing distances and lower stall speed, has created a need for the comparative analysis of the performance of different high lift airfoils. US Army has developed high-lift, low-speed AAI RQ-7 Shadow UAV of such kind. Apart from the armies of various co...
Flow stagnation is an important hemodynamic feature in aneurysms and plays a major role in biochemical transport and thrombus formation. Several Eulerian and Lagrangian approaches have been used in the literature to quantify flow stagnation. However, the connection between these approaches is not obvious, and the physiological implication of each m...
Transcatheter aortic valve replacement (TAVR) has rapidly displaced surgical aortic valve replacement (SAVR). However, certain post-TAVR complications persist, with cardiac conduction abnormalities (CCA) being one of the major ones. The elevated pressure exerted by the TAVR stent onto the conduction fibers situated between the aortic annulus and th...

TAVR has emerged as a standard approach for treating severe aortic stenosis patients. However, it is associated with several clinical complications, including subclinical leaflet thrombosis characterized by Hypoattenuated Leaflet Thickening (HALT). A rigorous analysis of TAVR device thrombogenicity considering anatomical variations is essential for...

Background:
Cardiac conduction abnormality (CCA)- one of the major persistent complications associated with transcatheter aortic valve replacement (TAVR) may lead to permanent pacemaker implantation. Localized stresses exerted by the device frame on the membranous septum (MS) which lies between the aortic annulus and the bundle of His, may disturb...
• The maximum area-weighted average log ε and area-weighted average log ε at the end time step of TAVR simulation in the MS region of the PPM patient shows significantly higher value than that of the control patient.
• This study successfully verifies post-TAVR CCA occurrence and the need of PPI for the selected patient cases.
• The results indic...
Transfusion ensures restoration of sufficient blood and blood components to treat the sick and injured. Voluntary blood donation is a safe and effective means of life-saving in many medical situations. Between February 2016 and February 2017 a total of 4456 units of voluntarily donated blood were collected by Chittagong Medical College. This descri...
The Electronics industry is continually strives to achieve improve performance and smaller scales. Both of these targets result in increased heat flux densities within the electronic devices. Mainly from the portable devices which are the market driving forces; this increasing heat flux densities are leading to new methodologies being implemented t...

Has anyone modeled aortic valve calcium plaque crack/failure/fracture? What crack model works the best? Can you also guide me to a good resource where I can find reliable fracture parameters? TIA
Note: I am looking into the 'concrete smeared cracking model', 'concrete damaged plasticity model', and also ductile fracture models. The issue is I have not found any reliable source clearly stating the material property/ a range of property (since calcium deposit material property can vary based on age and some other hemodynamic factors). So I am unable to test out those models.
Are you going to do this experimentally? I have the code ready for simulating particle deposition in CFD domain (domain of interest). We could collaborate on this. :)
How to export volume mesh from ANSYS Fluent in .cdb format? Or Can the .msh file be converted to .cdb file? Thanks in advance
How to find the circumferential direction of surface elements using python code? Can you please give me a sample code or tell me the python command for this?
Can anyone please suggest me statistical analysis processes/functions other than probability density function & cumulative distribution function?
I want to make a python code for advection diffusion equation on a square. 0-Dirichlet BC on three sides and 0-Numann on one. If you have done this, could you please explain it briefly? Thank you
'Hoverbike' with two rotors experiences a sideward torque while moving forward. How can it be alleviated?
I am interested in designing and fabricating a RC VTOL aircraft. But it is very difficult to work alone. I need company. Is anybody interested in working with me?
