𝐂𝐡𝐚𝐫𝐚𝐜𝐭𝐞𝐫𝐢𝐳𝐢𝐧𝐠 𝐋𝐢𝐪𝐮𝐢𝐝 𝐃𝐢𝐬𝐩𝐞𝐫𝐬𝐢𝐨𝐧 𝐰𝐢𝐭𝐡 𝐀𝐧𝐬𝐲𝐬 𝐋𝐒-𝐃𝐲𝐧𝐚 Our engineer, Ivaylo Klecherov, recently conducted a comprehensive study using Ansys LS-Dyna, focusing on fluid-structure interaction methodologies. The aim was to capture high-speed water propagation and examine air and water phase interactions affecting water front deceleration due to air drag forces. 📚 Read More: https://lnkd.in/dmpvZCDB #FluidCodes #AnsysEliteChannelPartner #FluidDynamics #Simulation #EngineeringInnovation #AnsysStructures #LSDyna #FireSafety Ansys Structures

Computational Fluid Dynamics (CFD) is an increasingly valuable tool to gain deep insights and understanding of how vessels in full scale perform through simulations. During the recent #HullPic conference we were proud to have our specialist Zakari Midjiyawa presenting our work on #CFD to assess hull performance. His presentation titled "Assessing marine coating performance on full-scale ship using an experimental channel-flow setup” provided valuable insights into hydrodynamic performance and fuel efficiency of different coating types and roughness in a steady-state simulation of a container ship. By combining experimental techniques and simulations we are able to establish better understanding of the correlations between various surfaces and their influences on vessel performance in full scale. Through these methods we are able to show that surface resistance and ship resistance are dependent on multiple factors, not only surface roughness - giving us a unique tool to design and optimize our products and technologies.

I am pleased to share our new article published in International Journal of Thermal Sciences: “Effects of geometry on the thermal-fluid dynamics of a transition water flow in a square heated asymmetric cavity channel”. This is the last article as part of my PhD thesis and it is subsequent to the previous two published. In this work, the S* parameter introduced previously is identified as the penetration capacity of the recirculation in the boundary layer. Additionally, a range of attachment angles for the cavity channel geometry is identified for the most uniform and highest heat transfer performance.

CFD Tuesday In this weeks CFD Tuesday we are looking at a feature in STAR-CCM+ called Mesh morphing, combined with the isentropic gas relations.  The isentropic relation defines how the volume, density, pressure and temperature are related for a change in volume.   When we shrink the volume adiabatically, by moving the bottom wall up, we compress the gas, increasing the density, pressure and temperature. Then, when we increase the volume again, the density, pressure and temperature return to their original values.    This shows that mesh morphing is a good method to model this motion.    Although this is a simple example, there are (endless/many) applications for mesh morphing. Think about moving bodies like piston motions, vortex induced vibrations, or complex physics such as growing of ice #Femto #CFD #Mesh #Morphing #Weenableinnovation #Engineering

💹 Excited to share our latest paper published in the renowned "International Communications in Heat and Mass Transfer"! In this study, we employed innovative vortex generators called V-baffles inside heat exchangers to investigate local and average heat transfer rates within the pipe. CFD simulations were performed in Ansys 2023R1. The main findings are as follows: 🔹 The double-V-baffle creates impinging jets on the wall, enhancing the main vortex flows. 🔹 The double-V-baffle results in a higher Nusselt number (Nu) but significantly lower friction factor (f) compared to the single-V-baffle. 🔹 The double-V-baffle's effectiveness is up to 21% greater than the single-V-baffle.
