DESiM Innovations, established in 2022, is the brainchild of Abdul Nassar, a distinguished professional with over 27 years of multifaceted experience in the realms of Industry, Academia, and Research. His expertise spans turbomachinery design, aerodynamics, Computational Fluid Dynamics (CFD), and Heat Transfer.
Before laying the foundation for DESiM Innovations, Mr. Nassar played an instrumental role within a renowned turbomachinery design institution. There, he contributed significantly to the design and development of various turbomachinery components, including turbines, compressors, fans, and pumps.
In his capacity as a consultant, collaborating with several prominent OEMs, he actively supported the design and development of new products. This enriching experience has equipped him with extensive insights into the design, analysis, and optimization of turbomachinery across a spectrum of applications. Mr. Nassar’s illustrious career has set the foundation for DESiM Innovations to excel in delivering innovative solutions and consultancy services to our valued clientele.
Backed by strong leadership, our growing team brings together engineering expertise, innovation, and execution excellence to deliver reliable solutions.

I had the privilege of collaborating with DESiM Innovations (OPC) Private Limited and their exceptional team on multiple projects, including steam turbine blade design and CFD simulations, air particle separator, and cyclone separator simulations. Their expertise in these intricate fields is truly remarkable.
Mr. Abdul Nassar demonstrated a deep understanding of the complexities involved in turbomachinery applications. The CFD simulations they conducted played a pivotal role in optimizing our steam turbine’s efficiency, resulting in significant energy savings and improved performance. In the case of air particle separators and cyclone separators, their simulations were instrumental in fine-tuning our systems, enhancing our overall dust and particle separation efficiency, thus improving the overall system-level efficiency, and leading to a better-optimized design.
Their meticulous attention to detail, unwavering commitment to accuracy, and the ability to deliver results within stipulated timelines set them apart. The insightful recommendations and data-driven insights provided by Mr. Abdul Nassar allowed us to make informed design decisions, ultimately saving us time and resources.
I wholeheartedly recommend Mr. Abdul Nassar and their team for their outstanding engineering services. Their proficiency in CFD simulations and design optimization is truly exceptional. Working with them has undoubtedly elevated the quality and efficiency of our projects.

TurboTides has proven to be a highly capable and reliable tool for turbomachinery design and analysis. Its intuitive interface, combined with robust computational capabilities, allows for efficient development and optimization of complex components such as centrifugal compressors, axial and radial turbines.
What stands out is its ability to deliver accurate performance predictions while significantly reducing design iteration time. The flexibility in handling different operating conditions and design parameters makes it especially valuable for both preliminary design and detailed engineering work.
Overall, TurboTides is an excellent solution for engineers seeking precision, efficiency, and versatility in turbomachinery development.
We had an opportunity to work with DESiM Innovations for one of our special turbo pump design project.
Mr. Abdul Nassar helped us in designing the complete low suction head centrifugal pump with inducer, impeller, diffuser, and its complete assembly.
He performed in depth suitable pump configuration design and selection, design of all components which was well supported by detailed CFD analysis.
Abdul is well organized design consultant with a keen eye for the important details in engineering designs.
He provided us with positive technical support and that makes him a great partner to associate with.
