Diddordebau ymchwil
Mae fy niddordebau ymchwil mewn mecaneg hylifau nad ydynt yn Newtonaidd a dynameg hylifau cyfrifiadurol ac yn cynnwys modelu mathemategol hylifau cymhleth a datblygu technegau cyfrifiadurol ar gyfer rhagfynegi llif cymhleth. Mae fy ymchwil wedi cael ei ariannu gan y Cyngor Ymchwil Peirianneg a'r Gwyddorau Ffisegol ers 1985 ac rwyf hefyd wedi derbyn cyllid gan Ymddiriedolaeth Leverhulme, y Gymdeithas Frenhinol, yr UE a Diwydiant. Fy grant EPSRC sylweddol diweddaraf oedd Gwobr Partneriaeth Portffolio ym maes Hylifau Cymhleth a Llifoedd Cymhleth mewn cydweithrediad â'r Ysgol Peirianneg yn Abertawe. Mae'r wobr hon yn fy ngalluogi i ddatblygu modelu mathemategol ac offer efelychu rhifiadol ar gyfer cymwysiadau gan gynnwys iro a dynameg swigod cavitation. Ar hyn o bryd rwy'n cymryd rhan yng Nghonsortiwm y DU ar Wyddorau Peirianneg Mesoscale (UKCOMES) a ariennir gan EPSRC.
Mae fy ngwaith diweddaraf wedi ymwneud â datblygu modelau mathemategol ar gyfer hylifau viscoelastig cywasgadwy. Mae hyn wedi gofyn am ddealltwriaeth o thermodynameg systemau cymhleth. Rwyf hefyd yn gweithio ar y dull ffin trochi ar gyfer problemau rhyngweithio hylif-strwythur, dulliau rhifiadol ar gyfer llif aml-gam, cymwysiadau biofeddygol o ddeinameg swigod, modelu llif dŵr daear gan ddefnyddio elfennau cyfyngedig stocastig, dadelfennu cyffredinol priodol ar gyfer systemau eliptig ac ystod o dechnegau rhifiadol ar gyfer datrys hafaliad Fokker-Planck. Mae gen i ddiddordeb arbennig mewn dulliau elfennau sbectrol a'r dull Boltzmann dellt.

Bywgraffiad
Bywgraffiad
- BA - Mathemateg, Prifysgol Rhydychen, 1979.
- MSc - Mathemateg (modelu mathemategol a dadansoddi rhifiadol), Prifysgol Rhydychen, 1980.
- DPhil – Mathemateg, Prifysgol Rhydychen, 1983.
- MA – Prifysgol Rhydychen, 1987.
- DSc - Prifysgol Rhydychen, 2004.
Ar ôl graddio o Brifysgol Rhydychen, cefais fy mhenodi i gymrodoriaeth ymchwil yn ICASE (NASA Langley, UDA), cyn dechrau swydd academaidd yn Aberystwyth yn 1984. Cefais fy mhenodi i Gymrodoriaeth Athrawon ym Mhrifysgol Caerdydd yn 2004. Rwyf wedi dal athrawon gwadd ym Mhrifysgol Delaware (Peirianneg Gemegol) a'r Ecole Polytechnique Fédérale de Lausanne (Peirianneg Fecanyddol).
Rwyf wedi cyhoeddi dros 100 o bapurau mewn cyfnodolion rhyngwladol a dros 30 o bapurau mewn trafodion cynhadledd a adolygir gan gymheiriaid. Cyd-awdur un o'r monograffau ymchwil mwyaf blaenllaw yn fy maes - Rheoleg Gyfrifiadol - a gyhoeddwyd gan Imperial College Press yn 2002. Rwyf hefyd wedi cyhoeddi testun israddedig – Elfennau Mathemateg ar gyfer Economeg a Chyllid - a gyhoeddwyd gan Springer yn 2007. Cyhoeddwyd ail argraffiad o'r llyfr hwn ym mis Tachwedd 2023. Mae gen i brofiad sylweddol o oruchwylio ymchwilwyr ifanc (15 PDRAs a 28 o fyfyrwyr PhD).
