Review company-level records connected to Narayana Rao Chalasani before choosing the right outreach path.
With over 10 years of work experience in the field of mechanical engineering with an emphasis on thermal and heat transfer, I am a passionate and innovative Principal Research Engineer at Johns Manville, a leading manufacturer of insulation, roofing, and engineered products. My core competencies include product design, analysis, development, and optimization using advanced computational fluid dynamics (CFD) and finite element analysis (FEA) techniques. My mission is to create and enhance products that meet customer needs, improve energy efficiency, and reduce environmental impact. I enjoy working with cross-functional teams, collaborating with internal and external partners, and sharing my knowledge and expertise with others.In my current role, I lead the R&D product design life cycle, from ideation to validation, for new and existing products. I use ANSYS software to conduct 3D modeling, simulation, and testing of glass fiberizer, a key component of insulation products. I also provide recommendations for design enhancements, material selection, operational support, and failure analysis. I have developed and validated novel techniques and workflows that have increased the product performance, life, and reliability, while reducing the cost and time of prototypes and trials. I have also published several technical reports and presented my findings to research teams, customers, and senior management.

Littleton, Colorado, United States
- Lead R&D product design life cycle that included ideation, design analysis (CFD & FEA), engineering, material selection, product commissioning and performance, operational support, design verification and validation, failure analysis, end of life analysis and publish technical reports.
Littleton, Colorado, United States
- Lead R&D in developing new product technology and current product technology roadmap to enhance customer experience and organization bottom line.- Collaborate with cross functional teams (internal and external) from electrical and controls, materials and metallurgical, manufacturing, finance, project management etc., for product development.- Provide recommendations for design enhancements to meet product performance and operational support/technical expertise for manufacturing with root cause analysis. - Recommend, coordinate, and conduct trials and experiments to analyze data and product performance. The conclusions, recommendations and next steps are presented to research teams, customers, and senior leadership.- Continuous engagement with manufacturing, engineering, and industrial vendors to develop new/better materials for new/existing product development and performance.
Littleton, Colorado, United States
- Developed and validated a 3D thermal creep modeling technique in ANSYS Mechanical for accurately predicting glass fiberizer life. - Developed a full-scale 3D CFD model (~40 million cells) of glass fiberizer to accurately predict the performance and life. - Developed workflow in ANSYS Workbench resulting in increased CFD and FEA simulation modelling output by 500% and reduce prototypes and increase product life while reducing trials. - Compiled in depth literature on superalloys for material properties, creep properties, material structure and machining for developing more creep and corrosion resistant materials for products. - Technical lead for developing scope of work and technical specifications for the first computational cluster (128 cores, 1000 GB of memory) at Johns Manville.
Reno, Nevada, United States
- Technical peer review of research conducted by Pacific Northwest National Laboratory (PNNL) and National Institute of Standards and Technology (NIST) on thermal response of spent nuclear fuel packages to data from “Memorial Tunnel Fire Ventilation Test Program”.- Technical peer review included validating Container Analysis Fire Environment (CAFE) CFD computer code to Memorial Tunnel Fire Ventilation Test Program (MTFVTP) and other large scale fire experiments to use the CAFE CFD computer code as a tool to estimate the thermal responses of truck and rail sized Spent Nuclear Fuel Transportation/Storage Packages under severe accident conditions for Nuclear Regulatory Commission (NRC).
Reno, Nevada, United States
- Designed and built a replica of 8 x 8 boiling water reactor assembly between spacer plates using heater rods (spent nuclear fuel rods) and aluminum channel to measure the heater rod temperatures in vacuum, nitrogen and helium media. Developed a LabVIEW-based system to acquire and process time dependent thermocouple (~80 thermocouples) and pressure data. The measured data was used for the qualitative and quantitative benchmark and validation of ANSYS FLUENT to determine if CFD can be used as a design tool for spent nuclear fuel packages for United States Department of Energy (USDOE) and Nuclear Regulatory Commission (NRC).- Collaborated with Sandia National Laboratory for benchmarking and validation of in house developed fire CFD codes against experimental data from several Jet Propulsion Fuel Fire experiments conducted at Sandia National Laboratory in 1999.- CFD analysis of thermal protection provided by impact limiters to a containment seal with a nuclear waste transportation package in accordance to 10 CFD 71 for Nevada Department of Transportation.
