Tasneem M. Shah

Tasneem Mohammad Shah (Urdu: تسنیم محمد شاه‎), PhD, SI, TI, is a Pakistani scientist and a prominent mathematician who has made pioneering and instrumental research and contributions to the field of computational fluid dynamics (CFD) at Dr. A. Q. Khan Research Laboratories (KRL). Trained as an applied mathematician, his contributions include differential geometry, numerical analysis, information security, CFD-DEM model, hydrodynamics (of explosions), computer science, fluid mechanics, Vacuum Technology and CFD-DEM.

Tasneem Mohammad Shah was a pioneer and senior member of the Kahuta Project, and, along with Dr. G.D. Alam and Dr. Abdul Qadeer Khan, Dr. Tasneem Mohammad Shah have had worked out in the nuclear physics involved in gas centrifuge and the uranium based-device. As of today, he is a full professor and chairman 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 jubilant and newly founded university, the Quaid-i-Azam University where he received his undergraduate degree in mathematics from there. He did his MSc, M. Phil. from Quaid-I-Azam University, followed by his DPhil in mathematics from University of Oxford, United Kingdom.^[3] His doctoral thesis were written on "Analysis of Multi-Grid Methods, design, theory and development of Algo.".^[4]

M. Shah came back to Pakistan, after the 1971 Winter War where he joined his alma mater, Quaid-i-Azam University. His early research were mainly focused and emphasised on Fluid and Aerodynamics. In 1972, M. Shah was introduced by Asghar Qadir to Dr. Abdus Salam, where Professor Salam had delegated M. Shah to Pakistan Atomic Energy Commission where he had closely collaborated with Dr. Riazuddin and Dr. Asghar Qadir in the development of the nuclear device. At the end of 1975, Dr. A. Qadeer Khan had brought the drawings of the Zippe-type centrifuges, which according to Dr. Ghulam Dastagir Alam, were incomplete and the drawings of the centrifuge machine were incorrect.^[5] Dr. Anwar Ali then contacted Hafeez Qureshi to re-design and work out the solution of the Centrifuge machine. Hafeez Qureshi informed Munir Ahmad Khan (who later consulted with Dr. Abdus Salam) about the problem faced by the KRL scientists. Tasneem Mohammad Shah who specialised in Fluid dynamics from Oxford, was named by Dr. Abdus Salam for the gas-centrifuge project when Munir Ahmad Khan and Hafeez Qureshi consulted with him. In 1975, Anwar Ali and Dr. G.D. Alam had met with Tasneem Shah in Islamabad, and Shah, with the full backing of Abdus Salam, was accompanied by Dr. G. D. Alam to a secret project in Kahuta in 1975.^[6]

The following years, M. Shah had joined Abdul Qadeer Khan's then-known as Engineering Research Laboratories (ERL) from its beginning 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. M. Shah, a pioneer in fluid dynamics, had used complex integrations, and mathematical methods to developed the sustainable method for the gas-centrifuges which he published his work at the KRL.

He gained fame in the research laboratory when Dr. M. Shah had mathematically modelled the fuild system in a Zippe-type centrifuge, and have had improved the technology that was brought by Dr. Abdul Qadeer Khan in mid 1970s. His developed theories and the 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 complex and difficult 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 28 May 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 begun 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.^[7] 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".^[8]

Research

Monte Carlo simulation

The Monte Carlo method is a class of modern computation mathematics that analyses repeated simulations of random events. It often uses computer simulation to compute the results of physics systems. Tasneem Mohammad Shah's research applied the Monte Carlo method to the field of thermal radiative transfer^[9] and radionuclide enrichment technology. He also used the Monte Carlo method to solve problems in missile development affecting high-temperature combustion chambers and explosive weapon warhead.

Computation fluid dynamics

Dr. Tasneem Mohammad Shah was a pioneering scientist in KRL who launched the research programs to the field of Computational Fluid Dynamics (CFD) at Dr. A. Q. Khan Research Laboratories (KRL). 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 Computation Fluid Dynamics 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.^[10] 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 generally difficult to model mathematically the thermal and fluid systems accurately as the core consists of both high-temperature thermal fluid flow behaviour in a reactor core.^[11] Dr. T.M. Shah's publication and studies are considered one of the groundbreaking contributions to computational fluid dynamics in KRL due to its emphasise 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.
