Kenneth Walters FRS[2] (14 September 1934 – 28 March 2022)[3] was a British mathematician and rheologist.
He was a Distinguished Research Professor at the Institute Of Mathematics, Physics and Computer Science of the Aberystwyth University.
He made advances in two major areas: the measurement of rheological properties, and the numerical solution of complex flows.
In the first area, he extended the theory of viscometric flows, carried out a searching analysis of sources of error in the principal instruments in current use, and was involved in industrial applications arising in the manufacture of lubricants, detergents and paints.
Their mutual faith led them into lay leadership at St Michael's Anglican church in Aberystwyth.
