Tasneem M. Shah, Ph.D., SI, TI, is a Pakistani nuclear scientist and prominent a mathematician who has made pionnering and instrumental research and contribution to the field of Computational Fluid Dynamics (CFD) at Dr. A. Q. Khan Research Laboratories (KRL). He has made in a vast range of fields covered in Mathematical Sciences, including Differential geometry, Numerical analysis, Information Security, CFD-DEM model, hydrodynamics (of explosions), Computer science, Fluid mechanics, Vacuum Technology and CFD-DEM.

Shah was a pioneer and key member of the Kahuta Project, and, along with dr. G.D. Alam and Dr. Abdul Qadeer Khan, Tasneem Shah have had worked out in the nuclear physics involved in Gas centrifuge and the Uranium device. He is a full professor and chaiman of the Department of Mathematics at the Air University^[1][2].

Biography

Shah was born in Pakistan and had moved to Islamabad for his studies. He attended the jublient and newly founded university, the Quaid-i-Azam University where he recieved his undergraduate degree in mathematics from there. He did his M.Sc., M. Phil. from Quaid-I-Azam University, followed by his D.Phil. in mathematics from University of Oxford, United Kingdom^[3]. His doctoral thesis were written on "Design, Theory and Development of Algo, Algorithmic Graph theory"^[4].

Shah joined then-known as Engineering Research Laboratories from its begaining years. Trained as an applied mathematician, Shah was an instrumental carrying out the experimental and theoretical research at KRL. He was the founder and had served as the first director of the Computational Fluid Dynamics Division at the KRL. In particular, he had developed the expertise techniques in fluid explosions—phenomena which are difficult to model mathematically. He gained fame in the research laboratory when Dr. Shah had mathematically modeled the fuild system in a Zippe-type centrifuge, and have had improved the technology. His developed theories and experimental research led to an improvement in the devices, and KRL had developed the advanced and newer versions of the Zippe-type technology as P-1 and P-2. M. Shah's principal contribution to the gas-centrifuge program was the rotational dynamics of the ²³⁵U by using the applications of Washer and Shell integrations.

Dr. T. M. Shah was one of the key scientist who had helped developing the Inertial and Thermal system of the Ghauri missile system series. He had laid down the ground work of the Liquid-propellant rocketry system and formulated the various mathematical theories of the rocket science. On May 28 1998, with numerous other KRL and PAEC weapon scientists, M. Shah was an eyewitness to the first atomic weapons testing, at Ras Koh Hills near at Chagai Hills. He, along with other scientists, was conferred with high civilian awards in 1998, and in 1999.

After serving in KRL for more than 27 years, M. Shah had began providing training and teaching at the KRL to the field of Fluid dynamics. He established the Department of Cryptology at NUST whereas he served as its first director. He also established the first IT University in private corporate sector and become the first Rector of KASBIT, Karachi^[5]. He remained Dean, Faculty of Computer Sciences at Bahria University and established an Integrated Scientific and Industrial Software house for contract research (ISIS). He is the author of 14 Research papers. He is also working for establishment of an HEC project, "National Institute of Vacuum Science and technology"^[6].

Research

Monte Carly Simulation

The Monte Carlo simulation are a class of modern computation mathematics that are rely on repeated random in a often used in simulating physical and mathematical systems to compute their results. Tasneem M. Shah's research is focused more in the applications of Monte Carlo method to the field of thermal radiative tranfer. During his time in KRL, Shah had richly contributed to the development and undertaking the research to the field of Monte Carlo method^[7]. At KRL, he produces Monte Carlo Simulation in Thermal Radiative Transfer: Method Review, Validation and Parameter Sensitivity, which heavily demonstrates the Monte Carlo methods in the Thermal-power plants^[8]. Through the intensive research in KRL, his contributions led to developed the computerized electronic of systems of the KRL-based missile program. He is considered a pioneering scientist who introduced the MC Method research in KRL. Tasneem Shah used the Monte-Carlo Method for solving thermal radiation problems, while approaching better methods in improving the enrichment technolgy. He also used MC method solving the problems affecting the missile's high-temperature combustion chambers and explosive weapon warhead.

Computation Fluid Dynamics

Dr. Tasneem M. Shah was a pioneering scientist at KRL who launched the research programs to the field of Computational Fluid Dynamics (CFD) in Dr. A. Q. Khan Research Laboratories. He made important contribution in the field of CFD and had published numerous papers while staying in KRL. One of his important contribution to CFD while applying the CFD in nuclear power technology. He did his research using Pakistan's nuclear power plants, notably Karachi Nuclear Power Plant. One of his major research publication is "An analysis and comparison of tube natural frequency modes with fluctuating force frequency from thermal cross-flow fluid in 300 MWE PWR", which analysis the CFD applications in nuclear power plants powered with a gross capacity of 300 MWe^[9]. His publication highly stressed the motion and the movement of the advanced fluid dynamics in a Nuclear reactor core. In a Reactor core, It is difficult to model mathematically the thermal and fluid systems accurately as ithe core consists of both high-temperation thermal fluid flow behavior in a reactor core^[10]. Dr. T.M. Shah's publication and studies are considered one of the groundbreaking contributions to computational fluid dynamics in KRL due to its emphasize on physical and mathematical understanding and insight into the fluid flow and heat transfer phenomena in a nuclear reactor core. His teaching and research has brought a groundbreaking change in the field of Computational Fluid Dynamics at Dr. A. Q. Khan Research.

Quotes

Mathematics is the life line of engineering. Engineering Mathematics has developed rapidly along technological progress. On the other hand, it has always been an important part of the business studies. As a result, developing specialised Mathematics courses to suit each Engineering and Management programme requires dedicated research and effort. The Faculty of Mathematics works in close collaboration with Engineering and Administrative Sciences departments for developing the required courses.^[11]
